Eek-A-Mouse, who plays tonight at the Coach House, is not only an imposing reggae star--the 6-foot-6 singer and deejay has no trouble commanding a stage--but he's also a walking sound-effects machine. His frequently comical performances are laced with his signature trilled "bing-bong-
biddley-bing-boms" and high-pitched "ai-yi-yis"--all used to get fans on their feet and moving to his pulsating reggae rhythms.
