If Peter Brötzmann has been showing something of a lyrical sweet-tooth in recent times – such as in his duet with American pedal-steel player, Heather Leigh – these two gnarly releases with a couple of Swiss bands provide plenty of opportunities for the German tenor warrior to show he's still just as full of piss and vinegar as ever. His work as part of the high-energy trio Full Blast has been ongoing for a number of years and this fifth album spotlights a deceptively sophisticated aesthetic: punkish electric bass and snapping drums wrench pained tenor altissimo from Brötzmann, all overlaid with a fine grit of abrasive studio electronics, creating a thrilling blast of keenly sculpted noise. With track titles like ‘Uterine Prolapse’ and ‘A Man With One Ball’, you just know that Defibrillator are going to be less concerned with subtlety. Their mix of queasily lumbering, electronically modified trombone, apocalyptically growling electronics and jittery percussion build a monumental edifice at which Brötzmann yips and snarls like an angry terrier. If he's less successfully integrated here than he is as part of Full Blast, it's undeniably invigorating to hear the incorrigible septuagenarian still enjoying himself in such a savage environment.
