I told Bish I would make a list of stuff I think he should look at so here.

Birds in Row - Weird Hardcore Punk
Camera Shy - Dream Pop / Shoegazey
The Chariot - REALLY weird Hardcore Punk. Like they break into trumpets and country sometimes just because. They keep mistakes in their recordings on purpose.
Chon - Mathrock kinda
Code Orange Kids - Mathy Hardcore Punk. They break into obscure/post rock transitions a lot. They did really cool stuff but their new album is ass.
The Fall of Troy - Post Hardcore / Mathrock. Please like them :(
Foxing - I don't know what this is.
La Dispute - Post Hardcore / Spoken-word
The Mars Volta - Post Hardcore / Experimental. You've probably heard this before.
Nothing - Shoegaze. A lot like Whirr.
Now, Now - Indie Rock
Six Gallery - Post Rock / Math rock. One of my all time favorite bands.
Sorority Noise - Sometimes post rock and sometimes pop punk????
Teen Suicide - Lo-fi emo / indie rock / noise. Every song is completely different from the other.
This Town Needs Guns - Math rock. Similar to Six Gallery.
Title Fight - Post Hardcore / Punk. One of my all time favorite bands for sure.
Touche Amore - Post Hardcore / Skramz.
Whirr - Shoegaze. One of my all time favorite bands.
