Both performances should not be missed. Pakistan-born Abbasi combines South Asian music & jazz--a truly fertile combination--so the 1/21 Shed gig should be as interesting as-->the 1/22 concert, which includes alto saxist Rudresh Mahantappa (a personal favorite) & dynamic pianist Vijay Iyer. (I'll be there for both)
Looking farther ahead, Jason Moran--my favorite pianist--appears at UNC 2/5 with his Bandwagon. Again, not to be missed.
