Great job. This works really well.

> "lofi home recordings with no electronic elements and harmonically complex"

Yielded a bunch of things I would have expected but after 5-6 'dig deeper' clicks there were lots of interesting artists I hadn't heard of before.

> "contemporary classical with no electronic elements and small chamber arrangements"

Lots of interesting results I hadn't heard of before.

> "obscure indie bands associated with Olympia, WA formed in the 1980s"

Very good list. Does the time/location-bound results very well.

I think it's a good companion to sites like RYM as a middle ground between 'best of' ratings lists and personally curated lists.
