Jaisu's been making rap beats for donkeys, starting with instrumentals in his bedroom and building up to working with Danny Brown and The J.U.S.T.I.C.E. League. His stuff's quite amazing – you could watch videos of him sampling and working an MPC, can of Irn-Bru by his side, for hours – and he's built up something of a cult following in the hip hop production worlds with his work.
The problem with Drum Circle (and the whole of 'A Short Album', at that) is that there isn't really a lot a writer can say about it besides the fact that it's amazingly-crafted music: just listen.
Astral Black release 'A Long Player' on April 27th 2015 (pre-order).
