If you trace the path of alto saxophonist Jim Snidero’s varied output for Savant, you’ll note transitions with regard to instrumentation and personnel: from organ combo to quartets with guitar or piano, to the animated quintet music of MD66 and Jubilation! Celebrating Cannonball Adderley (the latter co-led with trumpeter Jeremy Pelt). With Waves of Calm, due out March, the veteran altoist enters a mellower, more contemplative zone. But the title seems to suggest that Waves of Calm might coexist with other states of mind, perhaps less than calm. And that is true: Snidero intends this album in part as a son’s reflection on his father’s struggle with Parkinson’s Disease.
