Erik Hall isn’t 18 musicians, but you could be forgiven for thinking that he is. He’s recorded music as a solo artist and with the group In Tall Buildings; before that, he also had stints in His Name Is Alive and NOMO. For his new album, he opted for a particularly ambitious maneuver: recording Steve Reich’s Music For 18 Musicians. The ensuing record is both a loving version of a minimalist classic and a work that shows the impressive flexibility within Reich’s composition. I talked with Hall about the making of this album and his own musical journey over the years.
