Although subtitled Still More Ultimate '66 garage classics!, not all of the recordings on the album were originally released in 1966.

The cover drawing is a colored version of the cover of the Pebbles, Volume 11 LP, the first album in the Pebbles series that was released by AIP Records.

For instance, Mike Stax in his 1998 review of Essential Pebbles, Volume 1 in the Ugly Things fanzine, groused: "Unfortunately also, we're left in the dark regarding any info on these groups".

"More than I Have" is an inventive psychedelic recording that was one of the best tracks on the higher numbered volumes in the Pebbles series and comes from a demo tape supplied by the band.

"That Creature" is a bad-taste recording that includes the line "Leave that ugly thing from another planet", courtesy of a band from Georgia.
