Doo Rag
One of the most bizarre Peel Sessions I ever heard was by Doo Rag, from Arizona. An unholy blues-derived racket featuring little in the way of melody, rhythm or even blues.
Doo Rag were a stunning apocalyptic-blues duo comprising the magnificently named Bob Log III on guitar and vocals (sung through a film projector), and Thermos Malling on percussion (usually pots, pans, boxes etc.) Their Peel Session was apparently recorded over the telephone. They toured with a mobile pirate radio station which led to a prosecution in Germany for broadcasting their gig over the frequency of the leading German radio station.
Rectifier is an astounding example of their art. Taken from their Peel Session, this is a loud blues stomp, that almost enters a trance like state with the occasional guitar lick or percussive glitch. Most of their songs were shorter, but this is their anthem.
Bob Log III now performs solo, playing guitar, drums and singing into a telephone handset welded into a motorcycle helmet. His songs are all about playing guitar and drinking whisky. Oh, and tits.
