Calling Card is the sixth studio release by Irish singer/guitarist Rory Gallagher. A 1976 release, it was his second of four albums released on Chrysalis Records in the 1970s. Deep Purple/Rainbow bass guitarist Roger Glover co-produced with Gallagher: it was the first time that Gallagher worked with a "name" producer and the only successful such collaboration. It was also the last album Gallagher would do with Rod de'Ath (drums) and Lou Martin (keyboards).
