I've been a huge fan for years of a guy named Bob Drake. His music ranges from banjo-driven avant-hillbilly humorous H.P. Lovecraft miniatures to incredibly tight pop production to blistering noise, frequently within the space of a single 1-minute song.

In a word, utterly strange.
Most of these are less than a minute, and you owe it to yourself to listen.
