If you liked Eluvium you're going to love these too:
Balmorhea - Balmorhea (beautiful acoustic guitar driven music)
Balmorhea - Rivers Arms (acoustic guitar, with piano sprinklings here and there)
Peter Broderick - Float (neo classical stuff, mostly instrumental)
Max Richter - The Blue Notebooks (classical music utilizing piano, cello, violin, viola etc. with readings from Kafka's The Blue Octavo Notebooks...pretty fucking good)
Max Richter - Songs From Before (same as above, but with Robert Wyatt's readings of Haruki Murakami's text)
Tulsa Drone - Songs From A Mean Season (instrumental post rock with lots of instruments)
