Rutgers professor Abe Burton, 54, will blow some sax and lead his quartet this Sunday for free at 2:00 p.m. in Metuchen at the library. His 1994 Closest To The Sun debut and 1996 The Magician follow-up preceded his 2000 Cause and Effect where he switched from alto to tenor. His style has been described as a cross between Jackie McLean (his mentor) and John Coltrane.
