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.
