The Complex is the second full-length album by Blue Man Group, released in 2003. The album produced two singles, and debuted at #60 on the Billboard charts. As with the previous album, a DVD-Audio version was released, containing a high-definition (96 kHz/24-bit) 5.1 surround sound mix. The Allmusic review by Robert L. Doerschuk states "Although its inspirations, musical and conceptual, trace as far back as Kraftwerk, The Complex serves as a reminder that modern devices and glistening production values can be applied to the most primal creative instincts, if utilized by the right — blue — hands".
