a teenage celebration: 'Teenage Wasteland, yes! We're all wasted!'" Recording and release The repeating set of notes (known technically as ostinato) in "Baba O'Riley" that opens and underlies the song was derived from the Lifehouse concept, where Townshend wanted to input the vital signs and personality of Meher Baba into a synthesiser, which would then generate music based on that data. When this idea fell through, Townshend instead recorded a Lowrey Berkshire Deluxe TBO-1 organ using its marimba repeat feature to generate them. This modal approach was inspired by the work of minimalist composer Terry Riley. The song was derived from a nine-minute demo, which the band reconstructed. "Baba O'Riley" was initially 30 minutes in length, but was edited down to the "high points" of the track for Who's Next. The other parts of the song appeared on the third disc of Townshend's Lifehouse Chronicles as "Baba M1 (O'Riley 1st Movement 1971)" and "Baba M2 (2nd Movement Part 1 1971)". Dave Arbus, whose band East of Eden was recording in the same studio, was invited by Keith Moon to play the violin solo during the outro. In most live performances, this part is played instead by Daltrey on harmonica. "Baba O'Riley" was released in November 1971, as a single in several European countries. However, in the United Kingdom and the United States, it was released only as part of the album Who's Next. The song, however, became one of the band's most popular songs, as well as a popular staple of AOR radio, and remains on the classic rock radio canon. Reception and legacy "Baba O'Riley" appears at No. 159 on Rolling Stones list of "The 500 Greatest Songs of All Time". The song is in the Rock and Roll Hall of Fame as one of the 500 Songs That Shaped Rock and Roll. The band Pearl Jam regularly plays a cover of the song during concerts, and a readers' poll in Rolling Stone awarded this cover as #8 in their Greatest Live Cover Songs. "Baba O'Riley" was used as the theme song for the popular television series CSI: NY (2004–13); with each CSI series using a Who song as its theme. The song was also used in the One Tree Hill episode "Pictures of You" (season 4, episode 13). The live version of the song from the album Who's Last plays in the opening segment of the Miami Vice
