Dave Koz's first Summer Horns installment, from 2013, was an all-saxophone affair. Retaining Gerald Albright and Richard Elliot from that outing, Koz assembles another front line of marquee musicians for Summer Horns II: From A to Z, including new arrivals Rick Braun (trumpet) and Aubrey Logan (trombone/vocals), who contribute a brassier texture to the proceedings. The goal is less individual solo spotlights and more about the classic horn-section sound that prevailed in rock, pop, and soul of the ’60s and ’70s. The menu, therefore, is spot-on: Songs by Spiral Starecase, Earth, Wind & Fire, Paul Simon, and Stevie Wonder are arranged by session veteran Tom Scott, big-band leader Gordon Goodwin, or Tower of Power’s Greg Adams. (The subtitle, From A to Z, refers to the unlikely medley of “Take the ‘A’ Train” and JAY-Z’s “Roc Boys.”)
