Yes -in addition to being a brilliant animator and writer, Seth also sings (He has said that he was given voice training by a 90-year-old couple who had trained Frank Sinatra), plays the piano, and voices several characters on “Family Guy”,“American Dad” and a bear on “The Cleveland Show.”
Seth can also add ‘actor’ in a recurring role to his resume when the upcoming ABC sci-fi drama “Flash Forward” debuts this Fall.
