Triumvirat was a progressive rock band formed in 1969 in Cologne, Germany by keyboardist Hans-Jürgen Fritz, bassist Werner "Dick" Frangenberg, and drummer/lyricist Hans Bathelt. Frangenberg left in 1970 and was replaced by Hans Pape. They were signed by EMI Records and recorded the album, "Mediterranean Tales (Across The Waters)", released in 1972 on Harvest/EMI. During the making of the second album, "Illusions On A Double Dimple" (1974), Pape left and was replaced by Helmut Köllen. EMI sent a copy to Capitol Records who released the album in the U.S, where it received significant airplay. A U.S. tour followed with Triumvirat opening for Fleetwood Mac. The next album, "Spartacus" (1975), gave Triumvirat their greatest chart success.
