Now that Phosphorescent finally got their big breakthrough (blog breakthrough?) thanks to the rustic glow of 2007's Pride, frontman Matthew Houck has a narrow window of opportunity to get his music to a wider audience. Instead, he chose to release an album of Willie Nelson covers.

Now that Phosphorescent finally got their big breakthrough (blog breakthrough?) thanks to the rustic glow of 2007's Pride, frontman Matthew Houck has a narrow window of opportunity to get his music to a wider audience. Instead, he chose to release an album of Willie Nelson covers.

To Willie is intended as a nod to Nelson's own Lefty Frizell tribute, 1975's To Lefty From Willie. The music is as spare and intimate as Houck's original material, and he puts his own spin on Nelson's tunes, especially on the echo-chamber rendition of "Can I Sleep In Your Arms." But ultimately, there's less freak in this folk than Phosphorescent fans have come to expect.

The band is said to take an even different form on stage, infusing Houck's quiet ruminations with a roadhouse-worthy swagger. That's the show that's coming to The Summit with underground guitar hero Mike Bones.
