In 1980, a friend gave Rollins and MacKaye a copy of Black Flag's "Nervous Breakdown" EP. Rollins soon became a fan of the band, exchanging letters with bassist Chuck Dukowski and later inviting the band to stay in his parents' home when Black Flag toured the East Coast in December 1980. When Black Flag returned to the East Coast in 1981, Rollins attended as many of their concerts as he could. At an impromptu show in a New York bar, Black Flag's vocalist Dez Cadena allowed Rollins to sing "Clocked In", a song Rollins had asked the band to play in light of the fact that he had to drive back to Washington, D.C. to begin work.
