Rarely do pieces with exclamation marks in the title end well. Usually they’re a sign of desperate over-enthusiasm, and presage a pandering piece of peppy schlock, so determined to be relentlessly upbeat that all concerns for musical quality are cast carelessly aside. There are exceptions, but they’re few and far enough between that I approached Rehnqvist’s Arktis Arktis! with some trepidation. Happily, my misgivings were misguided.
