Looks like my suspisions were correct, he had attended a few jams/gym sessions with PKcali, but due to his fathers fame, his life has not gotten as much mention in the media, beyond being Bob Clark's son
For anyone on here that may have known Ariel, it looks like the memorial is tomorrow.
I'll post details when I have them, or you can visit pkcali.com as Cliff will be sure to post details there as well.
