Noah Haidu is a pianist who endows his debut, “Slipstream” (Posi-Tone) with a no-nonsense, straight-ahead groove, and it’s some of the best group jazz you can hear in 2011, thanks to a line-up of boffo contemporary players — trumpeter Jeremy Pelt and saxophonist Jon Irabagon, two neo-traditionalists who always blow hot and cool; bassist Chris Haney and drummer John Davis keep things tight and tuneful, and the great stickman, Willie Jones III, kicks it out on drums for three tracks.  Haidu boldly demonstrates his affection for the great acoustic jazz groups of the 50’s and 60’s, but his charts and adroit technique (“Break Tune”) shout modern jazz. The pianist proves that he’s an enterprising improviser, from the jaunty “Soulstep” and the trippy ballad, “Float,” to the romp and circumstance of “Just One Of Those Things.” It’s affirming to hear a pianist who’s chock full of ideas, with a stand out quintet that never outshines the leader.  (8 tracks; 49:19 minutes)
