Blues Traveler's aptly named fourth album, Four, released in September 1994, at first looked like a sales disappointment, but it rebounded in 1995 when "Run-Around," a single taken from it, became the group's first chart hit. "Run-Around" became one of the biggest singles of 1995, spending nearly a full year on the charts and sending Four into quintuple platinum status. As the group prepared the follow-up to Four, Blues Traveler released the live double album Live from the Fall in the summer of 1996. The group returned in the summer of 1997 with its fifth studio album, Straight on Till Morning. After completing his 1999 debut solo effort, Zygote, Popper — who'd been experiencing chest pains for months — was forced to undergo an angioplasty; weeks later, tragedy struck on August 20, 1999, when Sheehan was found dead in his New Orleans home. He was just 31 years old.
