Béla Fleck is parsing his commitments for the coming months. Beginning this week, he will take part in three shows performed with his wife and creative partner, Abigail Washburn, before the November arrival of Colorado Symphony concerts at Denver’s Boettcher Hall. Then, after welcoming the New Year, Fleck will head to India for a series of gigs with Zakir Hussain and Edgar Meyer featuring Rakesh Chaurasia.
