Annoyed by the relative softness of a band opening for Drug Church at recordBar last week, I hiked several blocks to catch a bit of Kansas City’s premier Bill Evans acolyte at Voo Lounge. The swing associated with pianist Michael Pagán is the pinnacle of American elegance. The Berlin based Swiss pianist Marie Krüttli is also capable of playing pretty. Joined by bassist Lukas Traxel and drummer Gautier Garrigue, Krüttli balances beauty with coarseness on the new album Scoria. Not beholden to American jazz tradition, Krüttli’s trio possesses a rhythmic and sonic freedom capable of shocking listeners in North America. Not free but altogether liberated, Scoria’s thorniest improvisations are no less ferocious than the repertoire of Drug Church.
