This is an interesting album due to the transitions of mood in an outstanding expression of Fusion. On "Wahoo!", Eero Koivistoinen Music Society journey from upbeat jams to serene compositions. In addition, each style they approach goes full throttle in it's emotional depth. Best believe, when it comes to The Funk Eero get super funky and when it comes to tranquil moments of Jazz Fusion, they offer something soothing for the soul. Put this obscure release up next to some of the best of 'em like Miles Davis, The Headhunters, etc.
