Lots of things and people seem to dissuade artists from full albums these days. Singles do far better on spotify and co than albums. Influencers have also made the case for not doing albums in the past.
Then there is the issue with having to rehearse and record multiple songs. That takes time and effort, whether you’re going for a full studio option of doing it DIY. I suppose, from talking to young bands, many are still having to hold down a full time job each. Its hard to commit.
If a band is really good the best thing we can do is support them, talk about them (which you have), buy their stuff when we can afford to etc.
Also some smaller acts tend to cover other bands material to fill in set lists.
