John Popper (born March 29, 1967) is an American musician and songwriter, known as the co-founder, lead vocalist, and frontman of the rock band Blues Traveler.

[9] Popper is a founding member of Blues Traveler, serving as the band's frontman with lead vocals and harmonica.

Blues Traveler crossed over into mainstream pop/rock radio success with their 1994 album, four, which garnered the group extensive media exposure.

In 1990, Popper began to perform occasional solo concerts in addition to touring with Blues Traveler.

Several songs that originated as Popper's solo pieces have become part of Blues Traveler's repertoire, and vice versa.

The subsequent tour was canceled midway due to poor ticket sales, and Popper instead took the time to focus on his health.

[citation needed] In 1992, Popper conceived the HORDE Festival as a venue to gain exposure for up-and-coming independent musicians.

[12] Popper took over in 1998 as frontman of jam-band supergroup Frogwings, which then released the live album Croakin' at Toad's.

[9] The group's self-titled debut from 429 Records was released in March 2011 and was produced by band member Jono Manson, who co-wrote much of the material.

[citation needed] The first single, "Something Sweet", written by Manson and Bruce Donnola, was released February 7, 2011, on iTunes.

Doctors at Cedars-Sinai Medical Center[21] performed an emergency angioplasty, which saved Popper's life; he had 95% arterial blockage.

[8][24][25] In August 2016, he announced a pending surgical procedure to repair collapsed vertebrae in his neck, necessitating the postponement and cancellation of some Blues Traveler shows.

[26][27] Popper is an avid collector of weaponry, including firearms, swords, and a working $10,000 American Civil War cannon.

[29][30] Popper is a supporter of Second Amendment rights and once appeared on an MTV-sponsored roundtable discussion on gun control, which included panelists from the Law Enforcement Alliance of America and Harvard's John F. Kennedy School of Government.

[37] Popper (with and without Blues Traveler) has played at conventions, fundraisers, and ceremonies for both Republican and Democratic politicians.

The vehicle had a stash of hidden compartments, which contained four rifles, nine handguns, a switchblade knife, a Taser, a set of brass knuckles, and night vision goggles.

[42][43] No charges were filed for the weapons, as they were all registered and securely locked away, and Popper was licensed to carry them, with the exception of the brass knuckles and switchblade knife, which he agreed to surrender.

In the book, among band exploits and a variety of topics, Popper discusses the group's rebound from the death of bassist Bobby Sheehan, the creation of the H.O.R.D.E.
