I can think of two: Mariana’s Trench and Ween. I discovered Mariana’s Trench in my late teens when I saw a music video on YouTube of the lead singer featuring in a song. I liked his voice, so I had to look him up. I knew of Ween from Ocean Man when I was a kid but didn’t discover them until I was 21 and decidedly listened to the rest of their discography, and I’m glad I did. I haven’t stopped listening to these two since.
