Calling Card is the sixth studio album and eighth album overall by Irish singer and guitarist Rory Gallagher. Released in 1976, it marked the second of four albums he released on Chrysalis Records during the 1970s. The album was co-produced by Gallagher and Roger Glover, the bassist for Deep Purple and Rainbow. This collaboration was notable as it was Gallagher's first experience working with a high profile producer and remains his only successful partnership of such collaboration.Calling Card also marked the end of an era for Gallagher's band, as it was the last album to feature Rod de'Ath on (drums) and Lou Martin on (keyboards). Following the Calling Card tour (1976-1977), Gallagher restructured his line up, retaining only his long-time bass guitarist Gerry McAvoy. He hired Ted McKenna as the new drummer, forming a revised power trio that became his core group from early 1978 until 1980
