Onetime members from a group called Rhinoceros came back together in 1972 to form a new rock band, the Blackstone Rangers. Because of circumstances, the guys soon shortened their name to the one-word title Blackstone. The lineup started out with lead singer John Finley, guitarists Danny Weis and Larry Leishman, pianist Michael Fonfara, and bassist Peter Hodgson. A short time later, drummer Richard Steinberg and musician Frank "Zeke" Sheppard were added to the roster.
Blackstone recorded its debut album in 1973, On the Line. The music critics found the first album less than pleasing, and soon group members Finley, Leishman, Hodgson, Sheppard, and Steinberg were all moving on to more lucrative projects. Weis and Fonfara tried to hang in there for a while longer with Blackstone, brining in some new blood to the group, like bassist John Prakash, singer Mike Stull, and drummer Penti "Whitey" Glan. The official end came in 1973, only a year after the band's creation.
