MUSIC: Flavorpill paints an intriguing picture of the come-back of Roky Erickson, '60s psychedelic rocker whose struggles with schizophrenia stalled his music career: "Tonight, revel in Erikson's gravelly, whiskey-soaked voice mingling with Okkervil River's harmonies, and witness the return of an Austin rock legend on the road to recovery."

SCIENCE: A few tickets are still available to BarBot 2012, in which robots will be at your service: "Chat up a snarky electronic bartender. Listen to some graceful tunes being played by robotic music makers. And, after downing your sixth martini, you can finally admit that it's the geeks who shall inherit the earth." (8 p.m. to Midnight, pariSoma, 169 11th Street)
