Novoselic, in rehearsal.Attn: PUSA/Nirvana/Elephant ear fans! Our friend Krist Novoselic — who you will recognize from the EMP exhibit Nirvana: Taking Punk to the Masses — will lend his AXE to Presidents of the United States of America set at the Southwest Washington Fair, Friday in Chehalis. Novoselic has a long history with the troublemaking alt-popper. In 2009 he joined the band on surf guitar at the Croc for a fundraiser for Dow Constantine. He also appeared on PUSA frontman Chris Ballew’s cover of Nirvana’s “Sliver” recorded by Ballew’s kids’ project, Caspar Babypants.The 8:30 p.m. set is FREE, and is the perfect opportunity to get a room (and meal) at McMenaminsOlympic Club while you’re seeing a show in Chehalis.
