It took me a little while to figure out how to tag this one, but once I got rolling it the similar artists flowed easily. Hopefully that makes for a nice playlist :)
Will Joseph Cook's "Hearse" is off an EP titled Proof Enough, which you can grab a copy of here. It's an upbeat and jazzy single that draws comparisons to the likes of John Mayer and Jamie Cullum -- not a bad starting point.
