Bloomington, Indianaís Johnny Socko, with Bad Rufus and Lesser Profits, Wednesday, June 21, at the Bluebird Theater, is proof that college basketball coach Bobby Knight isnít the only explosive entity to emerge from the Hoosier state. Now based in Indianapolis, Socko is currently on its own self-described rock-and-roll rampage (hopefully, there will be no choking of fans) on the heels of the groupís fourth album, appropriately titled Quatro. The CD -- like the bandís live approach -- is an electric smorgasbord that covers everything from í70s arena rock to bossa nova and lounge, power pop, Motown and rap. The moderately skanking sounds of groups like the Mighty Mighty Bosstones are found in the very non-ABBA-esque Danciní Queen:; elsewhere, hard-driving pop guitars, Beastie Boys grooves and even a little Robert Plant rock action make appearances. The band takes what it likes and puts it through the Socko musical meat grinder. So watch your fingers and toes, and donít get too close.
