THEATER: Nymph O' Mania, a modern twist on A Midsummer Night's Dream, opens tonight and runs through August 15. Set in a redwood forest in Northern California, the play features a wedding, an evil lumber company, hallucinogens, and tree nymphs, all of which make for quite an outrageous romp in the woods.

LITERARY: The students in WritersCorps present their new book, City of Stairways: A Poet's Field Guide to San Francisco, which is part travel guide and part literary anthology, packed with original poetry, photography, artwork, maps, and tips on the places to see and be seen in San Francisco.

MUSIC: Touring/collaborating musicians, AntonetteG and Tippy Canoe present “The Cupcake Diaries,” an act that features sister-like harmonies and a "merry-go-round" of guitar, ukulele, washboard and bass that propels their roots-pop sound. Special guest Olivia Mancini will also perform.
