An armful of grizzled troubadours, fresh-faced upstarts, and relative unknowns gathered Sunday to pay homage to the late Townes Van Zandt, illustrating the Texas singer-songwriter's influence on generations of country-tinged musicians.

As performers drew straws backstage to determine who was going to play what, the standing-room-only crowd was treated to th
