RYLEY WALKER & CHARLES RUMBACK - little common twist LPCharles Rumback and Ryley Walker are both known for their creativity and curious spirits. Rumback is a drummer in high demand in Chicagos free jazz circles, and a pillar of the second wave of improvisers in a scene first shaped by the legendary players like Sun Ra and the AACM. Walker draws deeply on other distinctly American styles, bringing a strong sense of folk tradition to his playing that is as arresting as his freewheeling performance style.
