What is the measure of an artist? And, how does one measure the art of Jon Bibbs? Is it through influences as varied as saxophonist Lester Young, opera singer Maria Callas, and funky multi-instrumentalist native son Michael “D’Angelo” Archer for music touched by everything from gospel quartet to the classical? Is it through the telling generosity of a man whose first album, True Story in 2001, was not even for himself, but for the engineering studies of a producer friend? Maybe one assesses an artist through the sheer volume of quality output with five well-received projects released over the last 17 years, including Red in 2003, the critically acclaimed breakthrough album that is the internationally beloved Unbreakable in 2005, the adventurous and deeply personal heartbreak of the iTunes and Amazon charting Ode to Old Flames in 2012 (peak: #11 & #14 R&B, respectively), the traditionalism of American Songbook standards through the minimalist Jazz Variations Live from New York in 2013.
