Rumba Cafe is the place most upstart roots-rockers perform when they blow through Columbus (like tumbleweeds, obviously). The tiny Summit Street bar breeds loyalty, so even when bands outgrow the space, they keep coming back. Fortunately, a partnership with The Bluestone means Rumba can keep reeling in acts like Justin Townes Earle and Lucero even when stuffing them inside Rumba becomes a fire hazard.
