Pretty much all of them. *hipster glasses*
One of them would have to be 01010101 or the self-titled by Portraits of Past. Not a very amazing name or anything for an album, but my God, the quality. It's full of unforgettable tracks.
Others would be the I Would Set Myself On Fire For You self-titled, the MRTA Benefit album by Anomie(a hardcore feminist "screamo" hardcore band, with an incredibly emotional, chaotic, crusty, musty, dusty, rain drenched, lo-fi, and amazing sound), Coaltar of the Deepers the Penguin e.p. Blood Stain Child the Epilson album. Melodies for the Devil by Amduscia, and quite a few others.
