Damn near anything from Tennyson, but their Telescope EP is something else. Collapse, Virgil, and Sleepwalk particularly for me are just

chef's kiss

Highly recommend it and pretty much everything they put out.

For something different but still in my opinion expertly mixed/mastered, "narrowcast." have put out a few songs and an EP that I've been really vibing with. They've got either I think an album or an EP releasing this Friday too!
