Thursday, August 22, 1968 closed the Grateful Dead's leg of BG-133 at the Fillmore West — the third and last Dead night, with Kaleidoscope and Albert Collins.

Kaleidoscope were a Los Angeles band and one of the genuine oddities of the period: David Lindley and Solomon Feldthouse leading a group that played Middle Eastern and Balkan modes alongside blues and jug-band material, on oud, saz, bouzouki and fiddle as readily as on guitar. Jimmy Page later called them his favourite band of the era. They never sold anything much and they turn up on Fillmore bills throughout 1968 because Graham kept booking them.

Albert Collins, third, was the Texas guitarist called the Iceman — a Telecaster tuned to an open minor chord, played with his fingers, producing a cold cutting tone nobody successfully imitated.

BG-133 covered two whole weeks and four headline legs on one double-sized sheet, and this night ends the third of them. Quicksilver took the last three nights beginning the following evening.
