Puscifer is a solo project of A Perfect Circle/Tool singer Maynard James Keenan. Its ever-changing lineup matches its musical unpredictability — Keenan has referred to the group as a “playground for the various voices in my head … a space with no clear or discernible goals” — the sole constant being Keenan’s astounding and confounding voice and imagination. They play Merrill Auditorium (20 Myrtle St., Portland) at 8 p.m., with opening act Luchafer (which may or may not be band members of Puscifer in Mexican wrestling masks, but probably is). Tix: $58-$68 (all ages). 842-0800. porttix.com.
