the first is the better known of the two but still pretty obscure - six piece from atlanta that makes a chaotic, sassy and funny blend of alt-metal, metalcore, and fall out boy-ish emo along with a few other unexpected genre experiments and sonic gags I will leave you to discover. I have listened to this an absurd number of times over the last 48hrs.

the second ambushed me outta nowhere, a quartet from south korea that churns out a spicy blend of space-rock, post-hardcore and doom metal that lands somewhere between hum, and so I watch you from afar, torche, and city of caterpillar among other bands I thought of. this one can be purchased from bandcamp for only a buck - totally worth it.
