By far the best song on the second disc of Ummagumma, which consists entirely of mostly hard-slogging solo pieces by each member of Pink Floyd, is Roger Waters' "Grantchester Meadows." The funniest, however, is the excellently titled "Several Species of Small Furry Animals Gathered Together in a Cave and Grooving With a Pict," Waters' other piece, which delivers exactly what the title promises and is one of only few intimations that this notorious sourpuss has a functioning sense of humor. A sort of absurd continuation of the pastoral "Grantchester Meadows," which fades out to the sound of birdsong, this tape-based piece slowly builds from its naturalistic origins into a surreal soundscape of freaky animal sounds, some of which sound oddly realistic and others of which are clearly Waters' voice sped up, looped, and otherwise manipulated. Toward the song's end, Waters' occasional collaborator Ron Geesin appears in the role of the Pict (the earliest known inhabitants of Geesin's native Scotland), delivering a nonsensical monologue in a thick put-on of a Scottish burr. As noted, it's an odd song, and one that doesn't repay frequent or careful re-listening, but it's one of Pink Floyd's funniest and most experimental works.
