When antisocial rage meets music, the result can be very gratifying; in this case, I'm talking about "Preschool" by Gang Green.
The Boston band leaves no room for guitar virtuosity and philosophical lyrics; listening to "Preschool" just makes you want to mosh for the entire album duration: ten songs, each about a minute long.
Many tracks are introduced by a caustic guitar played almost foolishly, followed by pounding drums and a very aggressive voice, schizophrenic solos, and powerful riffs repeated insistently and sometimes chaotically, characterizing this rapid album.
Cataloging "Preschool" with a simple genre can raise a lot of controversies; many call it Hardcore, others Speedcore, some even Skatepunk, or simply Punk.
The only certainty is that this is very fast music, which enthusiasts will appreciate.
