Wavy Gravy - activist, official clown for the Grateful Dead, inimitable local icon - is turning 75. So he’s throwing a party stuffed with legendary musicians, local icons, and good karma. 

Called the “perfect entertainer” by Lenny Bruce and “one of the better people on earth” by The Village Voice, his clown persona stemmed from his protesting days and the infallible logic that police are less likely to arrest someone in enormous floppy red shoes. If you’re wondering about the name, he was dubbed Wavy Gravy in 1969 by B.B. King and has introduced himself that way ever since. 

Featuring Bob Weir and Mickey Hart (The Grateful Dead), Chris Robinson (The Black Crowes), and Pete Sears (Jefferson Starship and Hot Tuna), Wavy Gravy's 75th birthday concert benefits Seva, an organization he co-founded with Ram Dass to help create sustainable solutions to poverty and disease. With an emphasis on blindness prevention and cure, Seva-supported programs have restored sight to more than three million people in Asia and Africa. 

May 14. Craneway Pavilion, 1414 South Harbor Way, Richmond. Tickets are $45-250 at inticketing.com.
