Formed while the four members were high school classmates in Princeton, New Jersey, Blues Traveler came of age after graduating to become one of the New York City’s biggest attractions. After releasing their self-titled debut, “Blues Traveler,” in 1990, the band took to the road, their base of dedicated followers steadily growing as they shared bills with bands such as Phish, Widespread Panic and the Dave Matthews Band. Then Popper had his epiphany: Why shouldn’t all these improv-based bands get together for a formal tour? And so was born the H.O.R.D.E. tour, beginning humbly in 1992, with eight East Coast dates, each averaging 7,500 fans. Five years later, it was a certified smash, having featured The Allman Brothers, The Black Crowes, Sheryl Crow and Melissa Etheridge, along with the original crop of bands. On their fourth studio record, the band was finally commercially acknowledged with two Top 10 singles, “Run-around” and “Hook,” and sold more than six million copies of the 1994 release “Four.” The group returned in 1997 with its fifth studio album, “Straight on Till Morning.” The new millennium saw a newly charged Blues Traveler, and their sixth record, “Bridge,” appeared in May 2001. The next winter, Blues Traveler released the live “What You and I Have Been Through.” “Truth Be Told “followed in 2003, and, “Live on the Rocks” appeared in 2004. The group then returned to the studio, eventually releasing “iBastardos!.” “Suzie Cracks the Whip” was released in 2012, and “Blow Up the Moon” arrived in 2015. Blues Traveler continues to play to sold out crowds all over the world.
