Man, good question but incredibly difficult answer. If you like straight-ahead indie rock, I'd say start with Two Conversations; if you like more atmospheric stuff, try Low Level Owl; if you like more experimental stuff try Peregrine; and if you like a mix of all of that, start with Sagarmatha. The End of the Ring Wars and Mare Vitalis are excellent as well, but have a much "younger" sound, if you can call it that.
I'll probably check out low level owl and sagarmatha. Thanks!
