If you know Nirvana and Soundgarden as poster groups for early Nineties grunge rock, count neck-breaking sludge quartet Mudhoney as the movement’s less-well-known founding member. Early signees of influential Seattle-born label Sub Pop, the garage punk pioneers land in Austin to celebrate the 35th anniversary of debut Superfuzz Bigmuff. Boasting primal growls on “Sweet Young Thing Ain’t Sweet No More” and slacker sing-a-longs like “Touch Me I’m Sick,” the 1988 collection writhes with pure thrashing angst – or, as their Bandcamp brags, “Anthems that fucked up a generation.” L.A.-based psych-kraut experimenters Hooveriii, of Levitation fest’s auxiliary label the Reverberation Appreciation Society, add additional fuzz.
