Query: Stark, unsettling comedy genius

Satirical comedy, with a whiff of performance art, Jam is hilarious, sometimes thought-provoking and often dark as hell.The more disturbing items can be too much for the timid and polarise opinion strongly, but it's not all shock and horror. Many sketches are laid-back and playful and the whole CD is rampantly surreal.Throughout the disc, the soundtrack plays an integral part, from chilling to chilled-out, underpinning the moods and scenes played out.If you like your humour intelligent, dark and non-PC, Blue Jam sits in a class of its own and will blow you away.
