Context paragraphs:
Bustin' Out: Bustin' Out is the second album by American country rock band Pure Prairie League, released by RCA Records in 1972 (see 1972 in music).  It features "Falling In and Out of Love," which ends in a segue to their hit song "Amie."  Amie then concludes with the main chorus of "Falling In and Out of Love."  Because of this interrelationship, many American classic rock and AOR radio stations play the pair of songs as a single track.  The album features a guest appearance by lead guitarist Mick Ronson on the track Angel No. 9.  The album ended up becoming far more popular a couple years after its release, during the height of the Country Rock, and Southern Rock boom of the mid-1970s.  By then, band leader Craig Fuller was no longer in the band due to draft board issues.  "Amie" was released as a single in 1973, and began receiving airplay mostly on college radio stations.

American Football (1999 album): American Football is the debut studio album by American rock band American Football.

With Brendan Gamble taking producer duties, the group recorded a self-titled album at Private Studios in Urbana, Illinois.  The album's sound is a throwback to early Joan of Arc, a band which Kinsella previously played drums in.  American Football focused on the interaction between two guitars after listening to Steve Reich.  A few of the songs were unfinished by the time the band got to the studio and decided to finish them there.
