Jason Isbell & the 400 Unit

As part of the three-headed songwriting monster of the Drive-by Truckers, Jason Isbell was overshadowed by Patterson Hood's grim, vivid, and vernacular Southern tales sung with an inimitable, scorched voice that could become a haunting howl.

That says more about Hood than Isbell, though. Isbell wrote some the Truckers' prettiest music, but the band has never been much about pretty. Its three-guitar attack and working-class outrage meant that Isbell's songwriting and singing contributions to Decoration Day, The Dirty South, and A Blessing & a Curse got largely lost. And the truth is that his vocals are probably better suited to the Eagles than the Truckers.

When Isbell in 2007 split from the band (by all accounts amicably), it freed his songs from the Southern-rock context and gave them the space to be appreciated on their own. And following a 2007 solo debut mostly recorded with his Drive-by Truckers bandmates, the new Jason Isbell & the 400 Unit - released in February - represents a clean break.
