Out of the Blue is the seventh studio album by the British rock group Electric Light Orchestra (ELO), released in October 1977. Written and produced by ELO frontman Jeff Lynne, the double album is among the most commercially successful records in the group's history, selling about 10 million copies worldwide by 2007. Jeff Lynne wrote the entire album in three and a half weeks after a sudden burst of creativity while hidden away in his rented chalet in the Swiss Alps. It took a further two months to record in Munich. Side three of the original double LP consisted of the symphonic Concerto for a Rainy Day, composed of four separate tracks which together made up a cohesive suite, instead of one continuous track. The inclement weather effects heard on "Concerto" were real and recorded by Lynne during a very rainy summer in Munich. It was one of the first pop albums to have an extensive use of the vocoder, and helped to popularize it. Side three of the release is subtitled Concerto for a Rainy Day, a four-track musical suite based on the weather and how it affects mood change, ending with the eventual sunshine and happiness of "Mr. Blue Sky". This was inspired by Lynne's experience while trying to write songs for the album against a torrential downpour of rain outside his Swiss Chalet. "Standin' in the Rain" opens the suite with a haunting keyboard over a recording of real rain, recorded by Jeff Lynne just outside his rented studio. Also heard at the 0:33 mark of the song, which marks the beginning of The Concerto, is thunder crackling in an unusual manner voicing the words "Concerto for a Rainy Day" by the band's keyboardist, Richard Tandy. At around the 1:07 mark, the staccato strings play a morse code spelling out "ELO". The band used the song to open their 1978 World Tour Out of the Blue concerts. "Big Wheels" forms the second part of the suite and continues with the theme of the weather and reflection. Apart from its inclusion on the Out of the Blue album, the song has never appeared on any of the band's compilations or as a B-side until 2000, when Lynne included it on the group's retrospective Flashback album. "Summer and Lightning" is the third song in the suite. The raining weather theme is continued throughout the track, though the mood and lyrics are more optimistic. "Mr. Blue Sky", an uplifting, lively song celebrating sunshine, is the finale of "Concerto for a Rainy Day" suite. Again, the Vocoder is used at the end of the track where, at the 4:54 mark, one can hear "Please turn me over" as it fades out. It is the only piece from the Concerto to be excerpted as a single. The large spaceship on the album's cover (by now symbolic of the group) was designed by Kosh with art by Shusei Nagaoka. It was based on the logo Kosh designed for ELO's previous album, A New World Record, and looks like the space station with a docking shuttle from 2001: A Space Odyssey (1968). The number JTLA 823 L2 which is featured on the shuttle arriving at the space station is the original catalogue number for the album. The album also included an insert of a cardboard cutout of the space station as well as a fold-out poster of the band members. The space theme was carried onto the live stage in the form of a huge glowing flying saucer stage set, inside which the band performed. The album had 4 million pre-ordered copies and quickly went multi-Platinum upon release. Out of the Blue spawned five hit singles in different countries, and was ELO's most commercially successful studio album. It was also the first double album in the history of the UK music charts to generate four top twenty hit singles. Lynne considers A New World Record and Out of the Blue to be the group's crowning achievements, and both sold extremely well, reaching multi-platinum according to RIAA Certification. Capital Radio and The Daily Mirror Rock and Pop Awards (forerunner to The Brit Awards) named it "Album of the Year" in 1978. Lynne received his first Ivor Novello award for Outstanding Contributions to British Music the same year. The US release of Out of the Blue was originally distributed by United Artists. This changed after United Artists Records was sold by Transamerica Corporation to an EMI Records-backed partnership, which triggered Jet Records' change of control clause in its distribution contract, and Jet shifted to CBS Records as its new distributor. American cut-out copies of Out of the Blue soon became widely available at discounted prices in record shops in the US and Canada shortly after the album's release, affecting the album's sales and triggering lawsuits by CBS and Jet. The suits were ultimately unsuccessful in stopping the discounted sales.

Volta is the sixth studio album by Icelandic singer Björk, released on 1 May 2007 by One Little Indian Records. A wide array of artists collaborated with Björk on material for the album, including longtime collaborator Mark Bell, along with new producers Timbaland and Danja. The album received positive reviews upon its initial release, and is Björk's first and only album to reach the top 10 on the US Billboard 200, peaking at number nine. Volta spent nine weeks at number one on the US Top Electronic Albums chart and in the first three months of release sold over half a million copies worldwide. In the United Kingdom it was certified Silver. The lead single, "Earth Intruders", reached number 67 on the UK Official Download Chart, and number 78 on the main UK Singles Chart, while the remix EP later charted on its own at number 150. In the United States, the song became her second entry on the US Billboard Hot 100 at number 84. Volta was nominated for Best Alternative Music Album at the 50th Annual Grammy Awards. The album was re-released in June 2009 in expanded versions, under the name Voltaïc. There were five separate versions of related material from Volta. The full version included a CD of 11 songs performed live at the Olympic Studios, a DVD of live performances in Paris and Reykjavík during the Volta tour, a second DVD of the Volta music videos, videos of the top ten runners-up from the "Innocence" video contest, and a second CD of remixes from Volta's singles. The official worldwide release date of all editions was 23 June 2009. The artwork was nominated for an award at the 2010 Brit Insurance Design Awards. It was a collaboration between the German fashion designer Bernhard Willhelm and British fashion photographer Nick Knight. Björk went on an 18-month tour in support of the album, which was her first tour in four years. In an interview with Pitchfork, Björk talked for the first time about the theme of the album: But with this one, it was different because I knew more emotionally what I wanted. And because I'd done two or three projects in a row that were quite serious, maybe I just needed to get that out of my system or something. So all I wanted to do for this album was just to have fun and do something that was full-bodied and really up. As the news of Björk's having worked with Timbaland spread across the Internet, many websites started speculating on whether the album would be "hip hop" flavoured; in one interview Timbaland himself referred to the upcoming album as "hip hop": It's crazy – I'm going tonight to go hear it. It's hip hop. I can't really describe it to you – if I had it right now I'd just play it to you. That's the best way for you to understand, and I'd let you tell me what it is.
