Bandcamp really is a treasure trove for finding releases of established and new independent artists. It seems that their business model is quite fair towards artists as well. It also seems that their acquisition by Epic games hasn't negatively affected them so far.
[Edit]: And they offer all downloads I've encountered so far in several lossy and lossless formats, including FLAC and WAV
Pretty much every metal band I discover, nowadays, is on bandcamp. I’m at 75 albums* and growing :) I really hope Epic won’t ruin it.
*: Mostly albums, some few are EPs or single tracks
That sounds like you need to try bandcamp, because they are missing the most popular stuff ;)
