This incredibly influential album was the first of its kind; as the original budget sampler, The Rock Machine Turns You On set a precedent that would be followed for over a decade, perhaps most notably by the series of Warner/Reprise Loss Leaders. Introducing a generation to “underground” artists, along with a cheaper way to get your hands on pop stars like Bob Dylan, The Byrds, and Simon & Garfunkel, it provided the mold to be followed by many later various artist compilations.
