This is the second “Jazz Marathon” put together by mainstream guitarist Doug MacDonald, and this two disc set of concert materials is filled with hard bopping fun. The warm toned 6 stringer teams with a pair of bands including Lanny Morgan/as, Pete Christlieb/ts, Ricky Woodard/ts, Carl Saunders/tp, Bob Summers/tp, Linda Small/tb, John Campbell/p, Josh Nelson/p, Jim Hughart/b, John B. Williams/b, Paul Kreibich/dr and Roy McCurdy/dr. All steady swingers living in LA, and the swinging is easy on takes of standards like “Our Delight” and the hip “Daahoud.” MacDonald is deft with the notes on a cool “’Round Midnight” and delicate “Whisper Not.” The rhythm teams do a delightful Latin lilt on “Con Alma” and hit the bop groove hard on “Blue Capers” and “Confirmation” with everyone getting a chance to solo on the stretched out pieces. This is the kind of stuff that made you fall in love with jazz; no fusion, no confusion.
