El Tri brings American Sign Language to Music in the Park

Music in the Park is back in San Jose with five shows downtown. The summer series kicks off this weekend with popular Mexican rock and roll band El Tri set to perform Saturday night. The group is doing something special, by incorporating American Sign Language interpreters into their performances in an effort to make them more accessible.
