Two thoughts.

One, a fellow Redditor pointed out recently that the Rick fanbase is a bit of a rigid one in terms of nostalgia. Oversaturation. There is already so much great stuff that new Rick bands have a harder time getting a foot in the door.

Second, apparently the average person stops exploring new music around their 30s. Let’s call them the passive consumers. Active consumers enjoy discovering new sounds and don’t wait for passive exposure through radio/tv/clubs/friends etc.

I’m sure there’s new Rick out there, you just gotta make an effort. A quick Spotify search gives me this 2022 playlist, 2nd 2022 playlist, 3rd 2022 playlist, best of 2019, best of 2018, best of 2017, best of 2020 and 2010’s rock anthems
