Matthew Houck — the man behind Phosphorescent — has been making music for over a decade, yet his 2013 Muchacho still manages to feel like a fresh variety of Houck’s signature lo-fi, folksy blues. It includes the entrancing melancholy lullabies of “Song For Zula” that immediately stood out as a new high water mark in the Phosphorescent catalogue. Except the gritty blues of his Alabama roots, a band that’s skilled enough to improvise, and elegantly constructed country ballads and jam outs.
