Last Exit, released in May 1969, is the third album by English rock band Traffic.
 It is a collection of odds and ends collected by Island Records after the initial breakup of the band.
 The first half of the album consists of studio recordings, while the second half was recorded live at the Fillmore Auditorium.
 The album reached number 19 in the American "Billboard 200" chart.
"Eyesight to the Blind" is a 12-bar blues song written and recorded in 1951 by Sonny Boy Williamson II (Aleck "Rice" Miller).
 He also recorded the related songs "Born Blind", "Unseeing Eye", "Don't Lose Your Eye", and "Unseen Eye" during his career.
 The Larks, an American rhythm and blues group, recorded the song, which reached number five on the R&B charts in 1951.
 Several musicians subsequently recorded it in a variety of styles.
 The Who used Williamson's lyrics for their adaptation for the rock opera "Tommy".
Tommy is the fourth studio album by the English rock band The Who, a double album first released in May 1969.
 The album was mostly composed by guitarist Pete Townshend as a rock opera that tells the story about a deaf, dumb and blind boy, including his experiences with life and his relationship with his family.
"Never Gonna Give You Up" is a song recorded by Japanese singer Mai Kuraki.
 It was released on June 7, 2000 in Japan as a CD single and as a 12" vinyl by Giza Studio, Giza Inc., and Tent House as the fourth and final single from her debut studio album, "Delicious Way" (2000).
 The track features lyrics in Japanese and English language, written by Kuraki and Michael Africk, respectively.
 He also served as the single's composer, backing singer and producer, alongside Kanonji, Miguel Sá Pessoa, and Perry Geyer.
 The CD release of the track included the B-side recording "Trying to Find My Way".
 Musically, "Never Gonna Give You Up" is an R&B and pop song whose lyrics delve on themes of love and relationships, a common trait on its parent album.
Beatles for Sale is the fourth studio album by the English rock band the Beatles.
 It was released on 4 December 1964 in the United Kingdom on EMI's Parlophone label.
 Eight of the album's fourteen tracks appeared on Capitol Records' concurrent release, "Beatles '65", issued in North America only.
 The album marked a departure from the ebullient tone that had characterised the Beatles' previous work, partly due to the band's exhaustion after a series of tours that had established them as a worldwide phenomenon in 1964.
 The songs introduced darker musical moods and more introspective lyrics, with John Lennon adopting an autobiographical perspective in compositions such as "I'm a Loser" and "No Reply".
 The album also reflected the twin influences of country music and Bob Dylan, whom the Beatles met in New York in August 1964.
Deep Purple In Rock, also known as In Rock, is the fourth studio album by English rock band Deep Purple, released on 3 June 1970.
 It was the first studio album recorded by the classic Mark II line-up.
 Rod Evans (vocals) and Nick Simper (bass) had been fired in June 1969 and were replaced by Ian Gillan and Roger Glover, respectively.
Crown of Creation is the fourth studio album by the San Francisco psychedelic rock band Jefferson Airplane, and was released in September 1968.
 It saw the band continuing their development of psychedelic music from their previous album, "After Bathing at Baxter's".
 The group had also been dabbling in electric rock with some references to science fiction in the lyrics.
 In most of their lyrics The Airplane expressed views regarding the hippie ethos, libertarian politics, and anti-war messages.
 For those reasons, they did not have a commercialized sound, and the singles the band released were not big hits.
 It would prove to be the pinnacle of The Airplane's psychedelic experimentation, for their next studio album, "Volunteers", explored more into country rock and hard rock.
Electronic Sound is the second studio album by English rock musician George Harrison.
 Released in May 1969, it was the last of two LPs issued on the Beatles' short-lived Zapple record label, a subsidiary of Apple Records that specialised in the avant-garde.
 The album is an experimental work comprising two lengthy pieces performed on a Moog synthesizer.
 Harrison subsequently introduced the instrument to the Beatles' sound, and the band featured synthesizer for the first time on their 1969 album "Abbey Road".
Pernice Brothers are an indie rock band.
 Formed by Joe Pernice in 1996 after the breakup of his old band, the Scud Mountain Boys, and including Joe's brother Bob Pernice (hence the 'Pernice Brothers'), the band recorded their first album, "Overcome by Happiness", for Sub Pop in 1998.
 After a 3-year hiatus (during which Joe Pernice recorded under his own name and as Chappaquiddick Skyline), Pernice Brothers returned in 2001 with "The World Won't End"; after parting with Sub Pop, the album was released on Pernice's own label, Ashmont Records, co-owned with his long-time manager Joyce Linehan, which in 2003 released "Yours, Mine and Ours".
 After a 2004 tour, the band released their first live album in early 2005, "Nobody's Watching/Nobody's Listening", and, in June of the same year, released their fourth studio album, "Discover a Lovelier You".
 The band released "Live a Little", their fifth studio album, in October 2006. "
Goodbye, Killer" was released in June 2010.
 The band is currently at work on a new album, but no release date has been decided.
 The band's songs are characterized by lilting melodies and intelligent lyrics.
