Tom Petty & The Heartbreakers released their self-titled debut album in 1976, but the feather-haired Petty and company had long since begun the process of perfecting their strain of Southern rock. Origins 1971-1978—this behemoth of a box set chock full of live recordings, extended versions of beloved hits, and never-before-heard material—provides a roadmap for those looking to retrace the steps of Petty & The Heartbreakers through their earliest recordings. But before the Heartbreakers, there was Mudcrutch, the Gainesville, Florida, rock act that Petty formed with future Heartbreakers Benmont Tench and Mike Campbell. The first of Origins’ five LPs, No Sleep Til L.A., debuts rare, newly mixed tracks featuring Petty and Mudcrutch: the lung-busting “Parade of Loons,” the foreboding “You’re Gonna Learn,” the lip-curling blues riffs of “Another Lonely Night,” and dusky ballad “Since You Said You Love Me,” which never materialized on an album (but has made an appearance on prior Heartbreakers compilations). The fifth, The Cut Out Bin, gives a glimpse into the first songwriting forays of a pre-Mudcrutch Petty, while the LPs in between include gussied-up versions of debut album Tom Petty and the Heartbreakers and its follow-up, 1978’s You’re Gonna Get It!, along with the complete recordings from 1977’s Live at the Record Plant.
