Wow, some great stuff happening here.
Abuse Patterns is pretty much spot on with the description. It sounds like mid-period Taint, some of Grunts works and Deathpile (but better). The sound is very well controlled and the recording/mixing is perfect for this style.
Machismo reminds me a little bit of some Bizarre Uproar mixed with very old Taint and maybe some STAB, but with it's own, unique brand of sickness. It sounds like it could be on Filth & Violence.
W hen I get the actual tapes I will do some full reviews on my site (and hopefully an interview), since I am reviewing these straight off mp3 which isn't always fair + that AP art/zine looks fucking great and could totally turn my head towards that direction when the context is laid out in from of me.
