Ha, that's brilliant that you spoke to them. I think they just need to have a constant clickable header that directs to the artist root page, which has the albums all laid out, then once you've clicked on an album you see the album page which has a little sub header that reads 'artist name - album/ep name
OK that's really easy to do. Go to your Bandcamp page and click on "index." Read the message in yellow at the top, and then click the link at the end. You will now have an index page that shows all of your releases, instead of just showing the latest one. You can then modify how many rows & columns are there. Problem solved.
