An almost unclassifiable mix of spare, bluesy vocals and powerful drumming -- with some pop and jazz elements mixed in for good measure -- Sweden's Wildbirds & Peacedrums feature singer Mariam Wallentin and drummer Andreas Werliin. Married in 2005, the couple released their full-fledged debut album, Heartcore, in 2006. Wildbirds & Peacedrums's second album, Snake, arrived in 2008 on the Swedish jazz label Caprice. ~ Heather Phares
