One of the other hot tickets at #NAMM2017 was the D’Angelico Guitars’ showcase Friday night featuring Bob Weir of the Grateful Dead, who debuted his new signature model acoustic on a set of old Dead tunes — including “Dark Star” and “Jack Straw” — as well as cuts from his new solo album, “Blue Mountain.” Weir was backed by a stellar band, including Matt Sorum of Guns N Roses, Jeff “Skunk” Baxter of the Doobie Brothers, and Gene Cornish of the Rascals. The show was only open to a small VIP crowd of some 150.
