Before coffeehouses became mainstream, corporate-owned hangouts, indie spots were the hub of choice (after bars) for artists and musicians to sip a cup of joe, socialize, create and connect. In L.A., the Onyx was the first authentic modern bohemian coffee spot, the place that defined Silver Lake for locals before outsiders made it a hipster haven. Owner John Leech opened the original location next to the Vista Theatre, then moved it to Vermont Avenue, where it became the Sequel, growing its loyal clientele (Beck, Keanu Reeves and Viggo Mortensen hung out or performed there). The place is missed, to say the least, so much so that reunions are organized every few years. This one is a two-parter. Experimental jams, spoken word, art and more from Onyx's past will be conjured on Friday at Cafe Nela (a pre-reunion live music show featuring arty acts including Tommy Chiffon Three, Mecalodiacs, Nostradumbass and Poisonous Members plus puppetry from Cinnamon Roll Gang). Then on Sunday, the Tribal Cafe hosts spoken readings, more jams and a barbecue in the back parking lot. Folk/punk/gospel trio The Mourners will play a set (with more TBA).
