Karolinka is a London-based group performing in "revivalist" style, backed by various instruments (frequent accordion leads). Some cuts are overarranged (particularly in the choruses), others are as close to the villages as any standard folk-festival group. The accordion aside, there is an excellent woman lead singer. It's not an ideal recording, but there is virtually no Polish traditional music available in the U.S.
