Lúnasa is back with a new studio album "Cas" and a tour of the US starting this February to celebrate their 20th Anniversary. It is their first studio album in seven years and it is also their first recording with vocals, including guest singers who are prominent artists in their own right, that the band has recorded and toured with over the years. These include Natalie Merchant and Mary Chapin Carpenter, top bluegrass singer/songwriter Tim O'Brien, Blues recording artist Eric Bibb and Daoiri Farrell, a young Irish folk singer star who recently won the BBC Radio 2 Folk contest. Lúnasa's inventive arrangements and bass driven grooves have steered Irish acoustic music into surprising new territory. Their recordings have been hailed as some of the best and most important world music albums anywhere, while their blend of intelligence, innovation, virtuosity and passion has brought them to the forefront of Celtic music. The new recording continues this tradition while bringing the listener forward.
