If the material on its brand-new EP Oversaturated is any indication, Brooklyn-based octet Rubblebucket has finally grown beyond its formative Afrobeat influences and arrived at its own unclassifiable sound. With each successive release, Rubblebucket’s core songwriters, Kalmia Traver and Alex Toth, have pulled the group into more daring territory while simultaneously sharpening their pop hooks. This time, the familiar ska and indie-dance hallmarks get completely subsumed by the songs — one of which even puts a fresh twist on slick, rushing ’80s-style production reminiscent of the Philip Bailey/Phil Collins hit “Easy Lover.” And that’s not to say that Rubblebucket has abandoned its bouncing backbeat or quirky presentation, only that those are no longer the band’s most prominent attributes. In fact, their current sound is becoming something more original and unique — a sound as inimitable as acts like the Police, Morphine, and TV On The Radio. Live, Rubblebucket hits exhilarating energy levels without ever slipping from impeccable execution.
