Top weekend shows: Os Mutantes, DJ Shadow, No Age
Os Mutantes: Brazil’s psychedelic pioneers, vilified by a repressive government in the ‘60s, have reunited in recent years, their music now widely acknowledged as an influence on everyone from David Byrne to Beck, 9 p.m. Friday with Ariel Pink’s Haunted Graffiti at Metro, 3730 N. Clark St., $21; etix.com.
DJ Shadow: Josh Davis is a master of sample-based composition; his mind-blowing 1996 album “Endtroducing …” remains a landmark, and on recent tour dates he’s been previewing tracks from his forthcoming 2011 release, 9 p.m. Friday at Park West, 322 W. Armitage, $30; extix.com.
No Age: Dean Spunt and Randy Randall explore the outer limits of what guitar and drums can do, with an abrasive mix of hardcore punk and electro-shock noise that makes their soaring melodies feel all the more surprising and satisfying, 7 p.m. Sunday at Lincoln Hall, 2424 N. Lincoln Av., $15; lincolnhallchicago.com.
