Bill Callahan is a singer/songwriter. He writes beautiful music, and sings in a subtle, simple baritone.
His lyrics are remarkable. His songs are deceptively simple. Everything about him is wonderful, including his weird, barely comprehensible epistolary novel "Letters to Emma Bowlcut"
Here is his 2009 album Sometimes I Wish We Were an Eagle, which takes it's title from that novel.
