The Day of Death is one of the most amazing experience you can get from a city like LA. Every year, during the week-end of Halloween, the Hollywood Cemetery becames the stage of the most candid and beautiful celebration of life and death I ever seen.
Jacknife has an amazing collection of tapes, vinyl, and used gear like stereos and tape decks. The quality is top notch, and if you can't find something out on the floor, chances are they'll have it in the back. If you see Trevor, tell him I sent you.
The LA Opera at the Dorothy Chandler Pavilion on Grand Street in downtown LA is a must during the fall and holiday season when they have a solid lineup of opera and ballet. Very inspiring.
