Vocalist Josh Groban's sixth studio album, 2013's All That Echoes, features more of the crossover classical music that has become his trademark, while pushing further than ever toward the pop end of the spectrum. This is largely due to producer Rob Cavallo (Green Day, Goo Goo Dolls, Paramore), who frames Groban's burnished croon in sweeping alt-rock arrangements that layer atmospheric guitar lines against grand orchestral segments. It also doesn't hurt that with every album, Groban has garnered more co-writing credits, adding to the intimate and personal vibe of All That Echoes. Tracks like leadoff single "Brave" and the dramatic ballad "False Alarms" bring to mind the yearning uplift of bands like U2 and OneRepublic, albeit helmed by Groban's crisp vocal intonation and soaring, resonant style.
