Best record store in the Boston Area hands down, and potentially the best record store I've been to.
Great selection of 60's/70's psych, folk, rock, pop, and oddities at dangerously reasonable prices. If you're a big fan of that stuff, there's lots of stuff to explore. A fair amount of their stock leans toward uncommon records, which is a great strength of the store if you're not intimidated. There's a fair amount of information and reccomendations written on stickers on plastic outer sleeves that gives you a good reference point or a strong recommendation from the store. So far the store's recommendations haven't steered me wrong and the recommendation/info/price stickers are almost always on an outer plastic sleeve if it's not in the bargain bin, but are really easy to cleanly remove if they're adhered to the record.
The store is extremely well curated and also well priced. Most stores will price something esoteric or rare high at first and then throughout months will mark it down to a sell-able price. But Deep Thoughts has everything priced to sell from the get-go. I typically don't buy albums I'm unfamiliar with, but I scored a lot of fantastic albums I would've never bought because I took a chance.
Their bargain bin is also a big draw for me as well. Quality albums that sold well but aren't particularly in high demand are plentiful. If you're looking for good copies of Laura Nyro, John Denver, Carpenters, etc, they have it for the exact price it should be. There's also a lot of more esoteric albums that may be in a bit of rougher shape but play well. There's also a decent amount of space dedicated to bargain bins, so there's a lot of quality cheap stuff to look through.
Not a fan of indie, metal, noise/experimental personally; so I can't comment on the quality of those sections, but they have an appropriate amount of store dedicated to them.
Staff has always been pleasant and friendly and it's in a great location with
Tres Gatos and Boomerangs close by.
TLDR: superb selection at superb prices. If you're a big fan of psychedelia or folk or someone looking for quality cheap stuff to start a collection hit them up.
