It makes sense that Innerpartysystem's visit to Off Broadway is being welcomed by the local dance party professionals at London Calling. It also makes sense that the dance-pop trio is on Red Bull Records. With eight-minute-long trance-rock dance songs, Innerpartysystem knows how to get a dance party started — and more important, knows how to keep it going. The new EP, Never Be Content, sounds a bit like Brandon Flowers collaborating with Daft Punk while playing Final Fantasy: it's full of rock-influenced robot dreamscapes. Combine that sound with the Innerpartysystem's infamous live performance lighting, and you have a show that will keep you dancing all night — or at least until Off Broadway locks up for the night.
