Michael Gallant is certainly a jack-of-all-trades—a Columbia University graduate who is a successful jazz pianist as well as an accomplished journalist, he has done it all. Gallant does not shy away from diversity in his music, either. On his latest release, Completely, he covers Pearl Jam’s “Go,” giving the grunge classic a bluesy twist. Completely is the first album that he recorded under the name Michael Gallant Trio, which also includes bassist Linda Oh and drummer Chris Infusino. Gallant can be seen performing Sept. 6 at The Record Collector in Bordentown.
