Lately when I've been in a chill kind of mood and need music, I go for the following:
*Warning - may contain jazz, new orleans funk, and the like
-Soulive
-Medeski Martin and Wood
-Stanton Moore
-Garage a Trois
-North Mississippi Allstars
and a very cool album that has John Medeski, Robert Randolph, and The North Mississippi Allstars entitled "The Word"
