Well, i have the first Umphrey's Mcgee Album, ill upload it later. Consider picking up their latest album, it is definitely worth paying for.
As for more chill bands:
Broken Social Scene
Moe (of course)
Robbers on High Street
Check out this band, the Longview Gunslingers
. They are a local band, one of my friends brothers is the guitarist. Honestly, one of the chillest bands ever, and their live concerts are insane.
Check out Artificial Feeling
and As the moon rises
, both are on their main website.
