Madhouse by Silver Convention

Madhouse is a 1976 album by German euro-disco group Silver Convention, which at the time consisted of vocalists Penny McLean, Ramona Wolf and Rhonda Heath, along with producer-songwriters Michael Kunze (aka Stephan Prager) and Sylvester Levay. The album is considered to be "funkier" than their previous releases". The album proved to be a moderate success, gaining considerable play at disco clubs at the time, but charted lower than Silver Convention's previous two releases, reaching number 65 on the Billboard Pop Albums chart, and number 47 on the Billboard Black Albums chart. The album has since been released on iTunes in several countries.
