Singer, songwriter, and guitarist Glen Phillips of Toad the Wet Sprocket was sitting on a glass-topped coffee table in the living room of Nickel Creek’s Sean Watkins, when the glass suddenly shattered, sending shards into the air and leaving Phillips with a severe cut on his left arm and a badly damaged ulnar nerve. (That’s the long, unprotected nerve in your forearm that tingles painfully when you hit your “funny bone.”) He also damaged a muscle in the arm. Watch above as Phillips discusses his injury in an exclusive Guitar Talk.
