SXSW...

The list of acts is growing. Notable ones for our purposes here:

Asylum Street Spankers (though I assume they're doing an adult show)
Steve Burns & the Struggle (ditto)
Daddy-A-Go-Go
Jon Langford And The Pine Valley Cosmonauts (of Mekons/Wee Hairy Beasties)
Joe McDermott
Tiny Masters of Today
Who Shot Hollywood

I know nothing about, but love the name of: Natalie Portman's Shaved Head
