Just in case you were beginning to have doubts about the state of jazz, along comes a group like that led by pianist Jill McCarron. The first indication that McCarron has done her homework is a look at her choice of tunes. For the most part she opts for unpanned gold like John Lewis’ “Concorde”, Sam Jones’ “One For Amos”, Kenny Dorham’s “Short Story”, Horace Silver’s “Cool Eyes” and a medley of two Bud Powell gems, “Glass Enclosure” and “Tempus Fugit”. McCarron displays a silvery touch, ease of improvisation, and a smart and sassy use of space. Her one standard on the session is a lovely, understated “My Ideal”. Her trio is completed by Paul Gill on bass and Andy Watson on drums. Here and there Will Anderson’s impressive alto sax and flute add a welcome presence. McCarron is the real deal. Never is there any overstatement or unnecessary flash. So here are some youngsters who have obviously put in the time. The result is a session that swings with enthusiasm and honors the tradition from note one.
