To honor what would have been the 20th birthday of Joaquin “Guac” Oliver (who was one of 17 killed at 2018’s Parkland school shooting) a number of premier acts will appear at Guacathon, a 20-hour facebook live event dedication to the prevention of gun violence.

Featured performers include Pearl Jam, Michael Franti, Twiddle and The Specials as well as politicians like Elizabeth Warren and athletes like Dwyane Wade.
