The album includes the band's usual repertoire of blues and R&B covers, while Frank Zappa contributed a song and played bass on two tracks.

It was the last album recorded by the original incarnation of the Animals prior to their disbandment, after which singer Eric Burdon would assemble a mostly new lineup under the name "Eric Burdon and the Animals".

A remastered bootlegged CD edition was issued by Flawed Gems[2][3] in 2014 that included 11 bonus tracks.

2014 CD reissue with bonus tracks (Tracks 1-12 are mono) Album credited only Eric Burdon, Chas Chandler, Dave Rowberry, Hilton Valentine, Barry Jenkins, and John Steel; Globalia.net credits others listed below for tracks 1 and 3 (LP and CD).

[5] The 2014 CD reissue has asterisks for tracks 1 and 3, but no explanation of them, so Globalia.net may be correct.
