NYC trio Consider the Source defy easy description. If intergalactic beings of pure energy, after initiation into an order of whirling dervishes, built some kind of pan-dimensional booty-shaking engine, powered by psychedelics and abstract math, it'd probably just sound like a CTS tribute band. Drawing from progressive rock, fusion and jazz, with alien sounds soaked in Indian and Middle Eastern styles, CTS blends disparate parts into a striking, utterly original whole.
