Ataxia is a supergroup featuring John Frusciante (RHCP) on guitar/vocals, Joe Lally (Fugazi) on bass and Josh Klinghoffer on drums. I've mentioned them a few times before and I know CA, RezZ and Kevorkian like them, but I think they deserve a thread.
Ataxia has released two albums and I'd recommend starting with their first (Automatic Writing) as it's the better one IMO... it was recorded in only 2 weeks. I really can't get enough of their sound even though I discovered them a couple of years ago. They're definitely a band which grows on you.
I'd describe them as minimalist first and foremost, but also mesmerising, visceral, intense, downbeat and slightly neurotic. Angular guitar over rumbling basslines with Frusciante howling over the top... not surprising as Public Image Ltd was apparently an influence on their first. I warn you that their music is nothing like RHCP, though that is probably a positive for some (Urban).
The Empty's Response - this is a really beautiful song, the mellowest one they've written.
The Sides - here's something with a bit more energy. I love the cathartic breaks and the dual leads in this.
Dust - this is a monstrous track.
