Grand Funk Railroad rose from the ashes of a local band in Flint, Michigan, called Terry Knight & The Pack, which included guitarist Mark Farner, drummer Donald Brewer, and singer Terry Knight. In 1968, Farner and Brewer recruited bassist Mel Schacher, thus forming the first lineup of this power trio, while Terry Knight took on the role of manager. Knight himself secured the band a performance at the prestigious Atlanta Pop Festival in mid-1969, achieving overwhelming success that earned them a contract with Capitol Records. Shortly after, they made their recording debut with their first album, "On Time", in which they superbly showcased their credentials with a vigorous and powerful style of hard rock with hints of blues and soul. Composed of ten songs, some featuring extensive instrumental passages like "Into the Sun", "Heartbreaker", and "T.N.U.C.", melodic and dynamic hard rock tracks like "Are You Ready?", intense blues rock like "Time Machine", and forays into the psychedelia prevalent at the time with the frenetic "Anybody's Answer" and "High on a Horse". A top ten hit on the Billboard charts and over a million copies sold made it one of the best debut albums in late 1960s rock music.
