I listen to a lot of folk music, both American (bluegrass) and Celtic, as well as Swedish 'Roots Rock' from groups such as Hendingarna
. Their label NorthSide
has an interesting compliation deal that they call 'Cheaper than Food', a series of CDs from all of their artists that they sell for $5.00 each, entitled Nordic Roots, Vol 1, 2, and 3. It is all in Swedish, but the instrumentals are amazing.
