One of the most iconic record stores ever is the Tower Records Sunset Location. I'm totally dating myself here, but I remember walking in there right around when I was first getting into music and being blown away by the sheer amount of music- mostly on cassettes and CDs at time. They had everything.
Lets go back to the same location about another 25 or so years earlier to 1971- yes sir, the glory days of vinyl. This video that popped up on Wax Poetics (via the Internet Archive) shows how deep their selection was. Stacks of wax everywhere - sort of like today's Costco - but instead of candy bars and Hot Pockets- you had music from Elton John, Linda Ronstadt and Joe Cocker And those 8-tracks tho-- Wow. If appreciate history, you're definitely going to dig this--
