There are a few live performances I keep going back to--to watch; the extraordinary kind, where the magic is as visual as musical. This is, to me, the strongest argument for making sure you go to see as much live music as you can. Take, for example, Steve Earle appearing with a cadre of other singer/songwriters paying tribute to Townes Van Zandt in 1997. While Earle plays "Ft. Worth Blues," the camera pans to Nanci Griffith, listening intently. Toward the end, it pans back again to capture tears streaming down her cheeks. Every time I watch it, they stream down mine.
