Fela Kuti-inspired afro-funk act Lovebush plays a free show at 8 p.m. at Siren's Song tonight after Arts Alive. Meanwhile, an hour later across the bay, you can join fuzzed-out wonders Hollow Down along with Dirt Magic and The Tweeners at the Jam for an evening of rock and pop and roll and then more rock, and maybe some jangly parts with vocal harmonies, some guitar solos here and there, and ... you get the idea ($5).
