Three is the magic number.

It's hip-hop Jim, but that's where the De la Soul comparisons end.

Edinburgh's motley collective of beatmakers, crate diggers, DJ’s, musicians and lyricists collectively known as the Penpushers are back to finish what they started with Poltergeeks, the final installment in the Our Golden Age of Inventiontrilogy.

This time round, the shadowy Scottish five piece voyage even further into uncharted sonic territory, having enlisted the otherworldly vocal talents of a certain Jane Gilbert aka Crazy Jane. As existing fans will be all too aware, you don't have to be mad to be a Penpusher, but it sure helps. Once again heavy on atmospheric instrumentation, razor sharp beats and laced with the ingenious po-mo flows of lead wordsmith Longface (why the long face?).

Of course, those fortunate enough to experience Poltergeeks will be compelled to investigate the Penpushers groundbreaking album Art Mechanics which along with sophomore work Void Engineers raised as many eyebrows with Wire readers as they did with the hip hop fraternity when the group opened for Public Enemy. All three albums feature the suitably skewed pen and ink skills of Scottish illustration whiz Bernie Reid, another excuse (as if you need it) to collect 'em all.

This is the future you see.

Darkly lyrical and musically crepuscular... a sense of monitoring a constant movement in the back streets of the city, the shadows of the mind and the depths of the soul. The Wire
