I'm glad you said who they were. I think the example of Sister Hazel perfectly fits the example I gave in another comment: it wasn't the case with them that they were a one hit wonder that flamed out quickly, but rather that they were a good band that made a lot of music that a lot of people liked, and one of their songs just happened to be a big radio hit.

AFAIK they really only had one song that "everybody" knows, "All for You", that got a ton of airplay. But they still put out a lot of records, they had a good devoted fan base of high school/college kids in the late 90s, and AFAIK are well respected for their music in the industry. Glad to hear they're still performing.

Belatedly coming back to this, but thank you for sharing! I'd not heard that name in a loooonnnngggg time and am currently enjoying the trip down memory lane.
