Proof Of Purchase 1st demoPROOF OF PURCHASE - NYHC. This was their 1st demo (they do have a new one out soon). 5 songs that sound like they were recorded from 2 tin cans and a shoe string. Bad recording aside, you got something pretty damn sick. 2 sisters in the band....one on drums, the other on vocals. Now that's different. And this aint no wimpy ass band either. Proof Purchase has the makings of a brutal "tough guy" style band. Well worth checking out if you're looking to hear something out of the ordinary "male" vocal style. Nothing weak here so dont be offended by it's heaviness. More info - Gigi/Mari 1339 Bristow St, Apt 4d, Bronx NY 10459
