I got the 'Hollow Man' sample, and I have been hanging out for this song ever since Jon said it was gonna be on Horror Show, but alas, it sounds quite generic, and probably not as good as anything on Horror Show. Is only a few minutes of it though, the whole song might be better. I haven't got the other 2 yet.
As for the vocals, Ripper actually sounds pretty good. I hope this vocal style can inspire Jon to write some more extreme material next time he is writing shit for the band.
