If you're looking for old records, House of Records is definitely a place to check. They have boxes upon boxes of old records, LPs, 45s, and more, organized by category and artist. Table after table of boxes! Thousands of records!
Special records on on display in the glass case, and some adorn the walls. Music-related posters can be found too.
There are 8-track tapes, cassettes, and even CDs.
The owners definitely know their chosen areas of music. Most of the time this is rock music, but they know about country and other kinds as well.
