Then there’s Traps and Taps at 2 p.m. Sunday at Alvas Showroom way down in San Pedro. Drummer Clayton Cameron and tap dancer Chester Whitmore run through the history of two extraordinary American percussive arts forms, drumming and American tap dancing, from the 19th century to the bebop era. It’s a subtle thing, percussion, but when these two show just how Max Roach and Bo Jangles Robinson did their thing it’ll open up a whole new perspective to you. Mixing the two might seem odd to a lot of people, but tap is all about percussion. Next time you mother insists on watching Easter Parade, wake up for Fred Astaire’s number “Drum Crazy”. He’s dancing and playing toy drums at the same time. Voila.
