Bandcamp mostly. They do writeups sometimes like “the best metal from Colorado” or “a deep dive into acid jazz”. They seem to be human written too and not ai slop, at least in the past.

Also seeing who’s playing with who. If I like band A, and band B is opening for them, well I’ll check out band B. I saw “Year of the Cobra” play with “The Well” and it was a good show, and I bought their album.
