Two of Portland’s top pianists will share a bill — and a band — in the next installment of Riverhouse Jazz on Friday and Saturday. In one corner, there’s Chicago native David Goldblatt, who once served as Diana Ross’ musical director and was bandleader on the short-lived “The Dennis Miller Show” in the ’90s. In the other is Darrell Grant, associate director of the School of Music at Portland State University who has played with Brian Blade, Tony Williams and Bill Frisell. Each brings a different approach to the instrument — from Grant’s classical and gospel explorations, to Goldblatt’s cinematic compositions (he’s scored a number of TV shows and movies over the years). The band — featuring drummer Chris Brown, bassist Dave Captein and saxophonist John Nastos — will back each pianist in turn. It’s a show tailor-made for music geeks who love nothing more than picking apart stylistic nuances — or anyone who just wants to hear some good, piano-driven jazz right before Christmas.

P.S.: Free Thursday jazz shows at Riverhouse will continue through the holidays, with Innovation Project (featuring Laz Glickman, son of Riverhouse Jazz founder Marshall Glickman) playing Thursday and Georges Bouhey’s Jazz Bros slated for Dec. 28.

Darrell Grant and David Goldblatt: 6:30 p.m. Friday and Saturday, doors open at 6 p.m.; $54; Riverhouse Jazz at Riverhouse on the Deschutes, 3075 NE 3rd St., Bend; riverhouse.com/jazz or 866-453-4480.
