Studio 301 Productions, the only student-run theatre group on campus, is flashing back to the ’60s, a time of flower children, free love and long hair — lots of hair, as in Hair: The American Tribal Love-Rock Musical.

The venue is the arboretum’s gazebo; playgoers should bring picnic blankets and-or lawn chairs. And be prepared for mature content and nudity.

More than 25 actors and singers are involved in the production, with Stephanie Hankinson as the director and Dave Moschler as the music director.

“We promise it will be Hair like never seen before, and, considering its strong theme of political activism, our production aligns symbolically with the recent protests and events concerning budget cuts affecting college students all over California,” said Alison Stevenson, publicity coordinator for the show.

Performances: April 28-May 2 and May 5-9, with all shows starting at 8 p.m. except for the two Sunday shows: May 2 and 9, starting at 7 p.m. Tickets: $14 general admission, $12 students ($13 and $11 for April 28, preview night).
