“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.
Other musicians who played with Acacia were drummer Eshan Khadaroo (Cirque Du Soleil, Blue Man Group, Psapp, Bow Wow Wow), guitarists Luca Ramelli and Maurizio Anzalone, and percussionist/world instrument player Ansuman Biswas (better known as a performance poet). Talvin Singh was also a member during the early days of the group.” Source
