Unlimited Devotion (aka UD) was conceived in Miami in April 2012 as a vehicle for exploring the Grateful Dead’s songbook. The band quickly developed a dedicated following and has steadily evolved its repertoire, personnel, and musical personality to reflect its current members’ jazz and funk influences.

Today, UD is based dually in Tampa/St. Petersburg and Miami. Its reputation for delivering energized, adventuresome performances has made the quintet one of the top drawing acts in Florida; a typical show routinely attracts 200 to 400 music fans.

In February 2018, Unlimited Devotion produced and performed Dead & Co.’s pre-concert and after party on Orlando’s famed Church Street. City officials estimated 5000 and 7000 attendees at the respective events, making it the biggest block party in Orlando’s history and earning UD national attention. UD was also named one of the top 4 most influential jam bands in Florida by Miami New Times Magazine in 2018 (along with Roosevelt Collier, The Heavy Pets and Snarky Puppy).

Dan began his musical training on piano at age 8. He started classical clarinet and jazz saxophone studies at ages 9 and 11, respectively, and continued both until age 17. In 1986, while attending the University of Virginia, Dan began working club dates as a drummer and singer.

Dan has shared stage with various notable artists, including Bo Diddley, Bob Margolin, Tom Constanten, Vince Welnick, Billy Payne, Paul Barrere, Fred Tackett, Mark Karan, JT Thomas, Tony Luca, Jake Shimabukuro, Christie Lenee, Michael Sokolowski, Kenny White, Scott Peace, Steve Connelly, Damon Fowler, Kenny Brooks, Reggie Scanlan and Roosevelt Collier.

Joe Falconeri: bass 


Joe was born in Brooklyn, NY, and raised in Queens. His was introduced to bass guitar at age 13, inspired by the styles of legends John Paul Jones, John Entwistle, and Paul McCartney. At 15, Joe discovered John Coltrane, and his musical world drastically changed. To increase his jazz knowledge, he began studying most notably with jazz legend Joe Solomon.

After moving to South Florida, Joe joined the Jerry Garcia tribute band Reflections in 2012, and a year later, Unlimited Devotion.


Darryl ‘Funky D’ Quesenberry: keys, vox 


A man of many monikers—Animal; Reverend Funky D; and, to FL east coasters, the godfather of St. Petersburg’s music community—D is an icon in Florida music circles. Since relocating to the Sunshine State from Virginia in 1990, he has helped grow the St. Pete scene.

D started his Florida run in the band Half-Baked Guru, which served as support act for the Spin Doctors during that band’s peak. He has led and/or been a member of many exceptional FL bands, including the Urban Gypsies, Food, The Funky Seeds, and Porcupine.

D first instrument was drums, but he transitioned full-time to keyboards over the years. His percussive sound is a recognized staple in the state’s growing festival scene, and his ability to orchestrate an ensemble on stage is admired and respected by players and fans alike. Notably, he is a mentor to many Tampa Bay-area musicians.


John Zias: lead guitar, vox 


John began playing at age 8 and performing at 11. He cut his teeth in the ’60s surf/psych scene. Attending his first Grateful Dead show in 1968 inspired his deep love for improvisation. The next year, he formed one of the earliest (the first?) Dead cover bands, Cavalry, with now-renowned songwriter Kenny White.

In 1974, John enrolled at Berklee College of Music, and his acquaintances at the conservatory included Pat Metheny, Mick Goodrick, Mike Stern and Bill Frisell. At Berklee, he became immersed in jazz theory and honed his improvisational skills.

John has shared stage and/or studio with: Phil Lesh; Rob Wasserman; Elliot Easton; Al DiMeola; Bill Frisell; Tom Constanten; Billy Payne; Paul Barrere; Doug Pettibone; Kermit Driscoll; John Molo; David Immergluck; Mark Karan; JT Thomas; Fred Tackett; Jeff Pevar; Michael Sokolowski; Chris Joyner; Kenny Brooks; Reggie Scanlan; Roosevelt Collier; and, Sokoband, featuring Tim Reynolds, Steve Kimock and Dave Matthews.


Al Zilinsky: rhythm guitar 


Al has been performing since the early 1980s when he made his way around New England with the band Sage and Spirit. In 1990, Al co-founded Crazy Fingers. In 1992, he started his own jam band, Toast n Jam, which played in South Florida until 1997. Business pursuits took him away from the stage until 2012 when he formed Unlimited Devotion.

Al also formed side project Funkin’ Grateful with members from the Heavy Pets, UD and Fusik. Their funky versions of Grateful Dead songs were a welcome addition to area music festivals.
