Sing it with me now — "Mmm bop, ba duba dop." That's right, we're talking about Hanson. Brothers Isaac, Taylor, and Zac's song "MMMBob" put them on the map, and their album, Middle of Nowhere, even earned them three Grammy nominations. Mercury Records made a documentary about the brothers, and they also have an authorized biography — and this is all before 1998. Due to a change in their label, their second album fell short in sales, and the boys eventually went independent. Regardless, the band kept touring and recording, and released their latest album String Theory in 2018.
