My thoughts so far:
When you have 2 people with such distinctive voices and writing styles, it's hard to truly consider this a new "band" album. With that in mind, I truly enjoy the album so far, I just can't mentally stop thinking of it more of a split album between Will and Dave. Though some songs, "Ghost To Be" and "Redback Strike," I can definitely hear more of a Bazan influence in the guitar/drums.
For those on the fence, with Dave occupying about half of the album, would you purchase an album if Dave put out a split with another artist? Even if you don't quite enjoy Will's tracks, you have a decent EP to listen to. Seems kind of silly to me that you enjoy Dave's work, post on a message board dedicated to his music, but question the need to purchase an album that he worked on. But to each their own I guess.
I do agree that it's enjoyable to hear them sing together on certain tracks, and wish there were more. I remember having that same thought on the Molina/Johnson split as well, sort of that same vibe. (Would totally be thrilled if Dave was contributing to the Molina tribute album by the way...)
