I've noticed that there are a load of new bands without albums and only a few songs.
I saw The Last Dinner Party at Latitude this year and I'm sure their set list was more than 2 songs according to Spotify/YouTube/website.
This goes for Lime Garden, Dead Pony, Divorce and Panic Shack just to name a few.
Yeah, I saw a bluegrass band called The Deer Creek Sharp Shooters at a festival last year. They played a full hour+ set but only had 3 songs available online anywhere. They said their album was coming later in 2022, but ultimately didn't release it until this year. A lot of the songs they played live were on that album.
