Swåp

Two Swedes and two Brits; two men and two women; two Nordic folk fiddlers and two traditional Celtic musicians. This is Swåp: the inevitable confluence of two distinct but related musical cultures. Their music moves effortlessly from Swedish polska to Irish jig, from Swedish "vals" to British waltz, with swinging arrangements, memorable original compositions, grace, respect and passion.
