We have posted several times recently about the next CD from Cadillac Sky, and the path it has taken along the way.

They have always fluttered along the fringes of multiple musical formats – so much so that categorizing their sound becomes an exercise in futility. They use bluegrass instrumentation, but the harmony and structure of their music owes as much to alt rock as it does to Bill Monroe. They had been recording for Skaggs Family Records, but their latest album was produced by Dan Auerbach of The Black Keys.

See a pattern developing?

This latest project, Letters In The Deep, was produced by the band on spec and they have decided to release it through Dualtone Records in Nashville. The official release date is June 8, but the C-Sky boys have banged heads with Dualtone and come up with an out-of-the-box twist on the box set concept, one that offers fans a chance to get more, in advance, before the packaged CDs hit the stores.

Three box set packages are available, all including a pre-release copy of the CD, a high fidelity copy of the album on vinyl, an exclusive T shirt, an immediate link for two audio downloads, and an autographed poster. You get all that for $39, and for another $50 they will also include a “Golden Ticket” that will get you into as many C-Sky shows as you make in 2010, plus prints of handwritten lyrics and musical notation from several songs. These packages will be shipped in early April.

For the very bestest fans, they have an Ultimate Box Set which includes everything listed above and a live acoustic concert for you and 50 of your friends anywhere in the continental US. For that you will pay $5000, and only five will be offered.

Bryan Simpson and Matt Menefee made up this back porch video to share the news of the new CD and the special offers.
