I've known of this band for many years thanks to the slightly proggy album they released in 1973 called In the Eye, their only official release (reissued in the 1990s), and note, it was dedicated to the once ultra famous Charles Bukowski now utterly forgotten. To my complete shock I found out recently that a collection of unreleased material from Screaming Gypsy Bandits came out called Back to Doghead, which was full-out progressive rock, and chronologically preceding the official release.
We're talking unusual harmonies, chord changes, abrupt tempo switches, gratuitous weirdness, etc. So for their personal history clearly they toned down the insanity of their roots for the record company.
Rot Nozzle has a distinctly Zappaesque influence, obviously:
I love how the track called Shells meanders its way through such a spacey atmosphere:
And the pentatonic electric guitar riff which starts out sounding so humdrum proceeds into uncharted territory quite soon enough on Medicine, evolving again throughout like the previous example into a much more grandiose thing:
There is quite a bit trash in here too, but that's to be expected.
