Although it was less critically acclaimed than their successful first two albums, Steppenwolf and The Second, it contains a few well-known hits, such as "It's Never Too Late" and "Jupiter's Child", as well as "Rock Me," which had been featured in the 1968 film Candy.

The album showcases Steppenwolf coming out of, but not yet completely abandoning, the psychedelia of The Second and stepping into the distinctive hard rock of their later releases.

The original LP was a gatefold with a punched-out front cover; the punchout revealed a photo of the band which comprised the inner sleeve's recto.

(A 1969 fire ripped through Canned Heat's house and rehearsal studio on Lookout Mountain Ave in Laurel Canyon, Los Angeles, California.)

The black-and-white portion of the album art was a collage made by Gary Burden, who planned to enlist Rick Griffin to paint a final version of the album art, but Dunhill Records declined to pay for the painting and so used Burden's black-and-white prototype.
