Acacia was a multi-cultural British experimental pop band active during the mid-1990s. The band is most notable for helping to launch the subsequent musical careers of several of its members, most notably keyboard player/producer Guy Sigsworth, singer Alexander "Blackmoth" Nilere and associate vocalist Imogen Heap (later a solo artist, half of Frou Frou and a collaborator with Urban Species and Jeff Beck). Though never commercially successful, Acacia attracted a good deal of underground attention during their existence and were notable for their eclectic musical approach and for Nilere's unorthodox, polysexual image.
