There is a LOT of stuff I've never heard of on here. But here;s what I've been listening to:
Rush - All The World's a Stage -
2112 era live album, worth listening to for some virtuoso playing. "Bastille Day" and "Anthem" are my favorites on this.
Les Claypool's Duo De Twang - Four Foot Shack - Ever wanted to know what Primus would sound like as a bluegrass band? Wonder no more. This album is pretty fun, but I don't think I'll go back to it very often.
Primus - The Desaturating Seven - Primus goes full Prog Rock on this, and it is glorious. Discordant, silly, and brilliant.
The Claypool Lennon Delirium - Lime and Limpid Green EP - Sean Lennon and Les Claypool cover some psychedelic classics like Pink Floyd and King Crimson on their second CD together, and it's a trip. Masterful.
GWAR - The Blood of Gods - GWAR can never die, and this album proves it. New lead scumdog, Blothar the Berzerker turns in a respectable first effort, and the songs are crass, vile, and hilarious, as always. Best tracks: "El Presidente," "Swarm," and "F***this Place."
