Altadena represent, yo!

OK, we're a middle aged dad-type guy who grew up in the 60's  and 70's, plays jazz piano and folk/classical guitar and doesn't understand modern music.  Be that as it may, "Evidence" is looking for people to appear in a music video to be shot in Altadena tomorrow.  You need to be dressed in funeral clothes.  The article with the details is here. We haven't a clue who any of these people in the article are.
