High Time was released on July 6, 1971, by
Atlantic Records. Dave Marsh wrote in the liner notes to the 1992 reissue:
Sadly, High Time's 1971 release represented the end of the line for MC5. Hard drugs had entered the band members' lives, and within a year they'd split up, drifting off into various other configurations. At least two members wound up in federal prison on drug charges, and they never did reunite before the untimely death of Rob Tyner in mid-summer 1992.
Although the band's debut album, Kick Out the Jams, had peaked at No. 30 on the Billboard 200 chart, their second album stalled at No. 137, and High Time fared even worse commercially.
