Jiha! I have found myself a new Hellfish & Producer cd. An older one this time. “Constant Mutation” may be a little less experimental than the other two cds that I have (see elsewhere), but this is only a little. The very positive side about this, is that there is more room for violent and constant beats, which makes this cd almost from the beginning until the end a very agressive piece of tekno. As ever brilliant and a must-buy!
