Slaraffenklang is a Danish big band made up of two great art-pop, etc. groups, Slaraffenland and Efterklang. After sharing bills in the U.S. last year as the Danish Dynamite Tour, they delivered the real thing in a one-time supercombo performance at home last fall. Four songs from that show are available as a free-download EP at the Leaf Label's MySpace page. I've been entranced by both bands separately. Together, they're like an entangled Animal Collective and Arcade Fire, with much more fire in the engine room.
