The band’s guitars hit some forceful crescendos, but fundamentally Lotion is as gentle as the kitten whose image graced its Kokopop debut. That’s why this New York outfit is right at home on Spin-Art, the little label whose explorations of the mild side of Amerindie-rock are actually underwritten by Sony. Lotion joins fellow Spin-Artistes Poole, Trampoline, and Ditch Croaker at a label showcase at 9:30 p.m. at the 9:30 Club, 930 F St. NW. $8. (202) 393-0930. (MJ)
