LA BOMBA DE TIEMPO
Centro Konex (Sarmiento 3131)
Mondays, starting at 8pm (get there early to wait in line and get in before they start). Brazilian style percussion, with about 10-15 band members playing various drums, etc. at once.
Great vibe, great energy, great music. HOWEVER, it's not low key. But I'm sure it's an experience they most likely haven't had before.
