Zac Hanson thinks of his band as just a bit out of step, in a good way. When Zac and his two older brothers formed Hanson as a teen pop band in the 1990s, grunge was the hot sound. As the trio’s music evolved, it was then out of step with the rhythmic pop sound that caught fire.

“Even today we almost sound like a 1970s band. We grew up listening to music from the ’50s and ’60s,” said Hanson of the Oklahoma-raised trio’s soul influences. “We don’t worry too much about what is popular and what is on the radio. We aren’t trying to sound like a disco band. Like it or hate it, music sounds like disco right now.”
