I live in the Los Angeles area and I don't miss Tower at all. At the time of their closing they didn't carry vinyl at all. In fact the last time the Sunset store had vinyl was in the early 90's. They also didn't carry used CD's and the new CD's they had were priced very high. There are alot of used record stores in the greater Los Angeles area.
Find a Record Collector magazine and they list over 30 stores that carry used vinyl. I was up in Ventura county last week which is about 75 miles west of the old Tower records store on Sunset. They have 5 stores that carry used vinyl. One store carries vinyl only and will throw you out if you ask for a CD. I'm also not missing Sam Goody's, Virgin records, Wherehouse, etc, etc. I like the fact that the mom and pop stores are back to selling vinyl.
It's a great time to be a record collector.
