No amount of conventional structuring is a prerequisite for a Can jam, but the Krautrock pioneers were certainly capable of gorgeous songwriting when so inclined, as well-exemplified by the fluttering "Sing Swan Song." This performance of the song from 1973 blows the song out to double-digit-minute length, but keeps its warbly beauty in tact throughout its extended sonic explorations, sounding like a Santana incantation echoed from a couple of rooms (or planets) away. Woulda loved to have the verse come back one more time at the end, but beggars can't be choosers with these things.
