I've turned into a real "adult contemporary" kind of dork in my late 30s. Been digging the new Beak> album a lot. My wife and I listen to a lot of The National and the Hold Steady. Wilco. All of it. I'm not ashamed. I even like U2.
Love singer-songwriters, too, Leonard Cohen and Dylan are big obvious ones. John Prine. Been loving Terry Allen lately.
Country/acid country: Sanford Clark, Buck Owens, Sir Douglas Quintet/Texas Tornadoes, Merle, Graham Parsons, etc
