Finland's TUM Records, both on disc and live at their annual Helsinki TUMfest, has been allowing musicians to explore their inner capabilities, expressions and dreams that may or may not be commercial enough to actually sell. The latest such offering, 'Celestial Weather,' features two such progressive, forward-thinking adventurers, John Lindberg on double-bass and Wadada Leo Smith on trumpet. It's an example of exotica, esoterica even.
