Tony Guerrero began playing trumpet at the age of nine. Actually, he thought his teacher had given him a trombone to play and after a few weeks of telling his parents he was playing the trombone, he was surprised when his dad actually saw the instrument and informed him that, indeed, it was a trumpet. By then, it was too late and he was hooked. While he took to it naturally, it was the inspiration of his junior high music teacher, Mark Takeuchi, that led him to fall in love with music and pursue it as a life-long passion.

His high school and college years were full of self-study, lessons and self-propelled band projects where he began to experiment with writing songs. His early love of artists such as Led Zeppellin and KISS had instilled a taste for rock'n'roll, and the music of Chuck Mangione introduced him to the idea that he could play rock-based music on the trumpet. Over the years he developed a love of jazz music and jazz artists. These influences, when combined with his many other musical influences, helped define his own writing and playing style.

As a kid he also began experimenting with other instruments, including the flute, clarinet, sax, drums, french horn, baritone, guitar, bass and piano.

By the time he began college, he was working six nights a week in local jazz clubs with much older and seasoned musicians who took him under their wings. Eventually, it was his own band, VISION, that caught the eye of a new original music label called White Light Productions. This led to the signing of his first record deal and to a long-lasting relationship with manager Lucille Hunt.

Tony's career as a noted recording artist began with the release of his first CD TIARA in 1988. This debut project introduced the world to his identifiable flugelhorn sound and his writing. The disc featured the talents of special guests Grant Geissman, Phil Keaggy, Max Bennett, Merry Clayton, Denny Correl and more, and gained national airplay on the strength of the hit "L.A.'d". Tony began his first forays into the touring world at this time, playing to new audiences around the country.

In 1989, the newly established artist released "Different Places", a popular radio favorite that featured the hit songs "Slam Shack", "Pancho", "Mangione" and more, as well as a veritable who's who of the new smooth-jazz scene, including Richard Smith, Norman Brown, Steve Reid, Brandon Fields, Brian Bromberg, Bill Cantos, Greg Vail and others. At this time, Tony was one of the only flugelhornists on the market - contemporary jazz radio blatantly admitted they weren't playing horn players in favor of sax, piano and guitar! But Tony's disc continued to receive substantial airplay.

In 1991, the release of his disc "Another Day, Another Dream" cemented his reputation as a leading and recognizable voice on his instrument. This disc featured the talents of Gerald Albright, Rob Mullins, Brian Bromberg, Bill Cantos and many more and was hugely popular on radio and with fans. His version of Quincy Jones' "The Secret Garden" received not only jazz station airplay but was featured in urban market stations right along side of Janet Jackson songs! The songs "Amorado" and "Another Day, Another Dream" were also widely popular. His touring schedule took him around the United States, Western & Eastern Europe, the South Pacific, Latin America & South America, culminating with a headling spot at the CanCun International Jazz Festival playing to over 25,000 people!

Over the following years, Tony has kept active in the studio as a guest on countless other artist's CDs and in concerts and club dates all over the world. He has continued to release solo CDs, including “Now & Then” (1995), “Mysterie” (1996), “Ballads” (2001), “Smooth Jazz At Midnight” (2002), “Christmas Songs w/ Bill Cantos” (2003), and has become established as a producer and composer in a variety of markets.

In the early 00's, Tony's band "The Hi-Fi Quintet" gained noteriety and substantial radio play by paying homage to America's classic music from Louis Armstrong to The Rat Pack. They released two CDs, "The Hi-Fi Quinet" (2003) and “This IS The Hi-Fi Quintet” (2008).

His first solo acoustic jazz CD, “Blue Room” (2010) received numerous rave reviews and substantial radio airplay around the country, spending nearly six solid months on the National Jazz Charts.

In 2014, Tony released "Reunion", a jazz duo CD with Dutch pianist, Frank Giebels, and 2015 saw the release of a brand new disc from The Tony Guerrero Quintet, "The Thing Is..."
