Reception. "Impose" described the collection as "a 20-tuned compilation of remixes, B-sides and obscure Wu material", with a "continuous swinging baseline", a "soulful musical setting which provide a fine contrast to the rappers lyrical grit", and "sounds that stem from the comforting  to the intimidating". Nevertheless, the magazine also described the collection as "appeal[ing] more to the Wu-head than the casual Wu-Tang fan". "Complex" called one song from the collection, "Maxine (Remix)", "told over a heavy-duty 1970s experience" but "smooth[ed ]out considerably with an easy-like-Sunday-morning groove". "HipHopDX" praised the compilation as a "testament to the knob twisting skills of Mathematics", but also stated that "the Clan's core members don’t make enough unheard appearances on the disc".
