Huntsville, Alabama-native John Hancock began playing the piano by ear at the age of two and was placed in formal classical lessons by his parents at age four. Over the years, his affinity for music resulted in the further development of his talents through a variety of other styles and instruments. 

John continued to study classical piano throughout his teenage years.  Following high school, he spent a semester studying as a double major in Piano and Vocal Performance at the University of Alabama in Huntsville. 

In 2003, John helped form the Celtic and folk band, Shillelagh, for which he sang lead male vocals and played rhythm guitar in northern Maryland.  The group covered mostly traditional Irish, Scottish, and English music, but also performed several of John's own originals.  Around the same time, John played keyboards for the local rock cover band, Oversize Load.   

In 2008, John wrote, recorded, and released his debut solo album, Sinners, Saints & Satellites, which he co-produced with Angela Taylor through his own label, Avila Publishing.  

In early 2013, John co-produced, again, with Angela Taylor, his second album, Irish Whiskey.  It was a project John had wanted to tackle for some time; all of the songs were considered traditional Celtic, most of which were Irish.  All songs were set to his original compositional arrangements.  

He currently resides in central California.

In regards to influences, as well as any preferred musical style, John generally chooses to explore all types, without limiting himself to any specific genre.
