Blues Traveler Frontman John Popper 'Memba Him?!

American musician and songwriter John Popper -- best known for his buttery vocals and crazy harmonica solos -- was 27 years old when his band, Blues Traveler, popped off in the mid-'90s with popular songs like "Hook" and "Run-Around!"

Two years after its release, Popper's composing brilliance scored him credit and recognition at the 1996 Grammys ... "Run-Around" won the award for Best Rock Performance by a Duo or Group with Vocal.

In 2016, Popper performed both of these hits for Bernie Sanders' "A Future to Believe In" rally.
