Kat Edmonson/Robert Ellis: Rams Head On Stage, Annapolis

KAT EDMONSON AND Robert Ellis, who brought their tour to Annapolis Tuesday night, are Houston singers with the same final initial and current Brooklyn addresses. But they share something even more singular than that: They are both attempting the difficult feat of combining singer-songwriter folk and sophisticated jazz. Their efforts have yielded two of the best albums of 2014 — Edmonson's The Big Picture and Ellis' The Lights from the Chemical Plant — and one of the best shows of early 2015.
