Cell15 is the brainchild of Robert Scott Richardson. In 2011, Robert had decided he wanted to write the progressive rock style that he loved. Raised on the great prog of the past, his love for “King Crimson”, “Gentle Giant”, “Yes”, “Genesis” and “Pink Floyd” influenced this musical decision. Twenty years of recovery had given him the subject matter, the advantage of owning his own recording studio gave him the place to work, and Cell15 was born. The idea of a concept album to tell the story of what happened twenty years ago to present served as the guide for where the music would go. “This is the first time I had the lyrics in mind before the music was written. I had to keep the focus on the story being told”, Robert said. The CD titled “Chapter One” had been released September 2014.

The debut release was well received internationally. Prog Rock radio stations were adding tracks to their playlists and an award was given as “Debut Album of the Year” on Prog In a review from House of affiliate Rob Rutz, Rob writes: “From the first recoil of the complex kit's snare drum, followed by locomotive-strength symphonic keys, listeners are propelled like shot in a sling into Cell15's powerful breakthrough debut album, "Chapter One." This is a driving progressive rock concept album that's befitting of the most-capable, well-powered sound system. Cell15's Chapter One album goes beyond masterful poly-rhythmic drums, full-bodied keyboards and driving bass, though. It's one hell of a story that portrays a dark life, capture and prison time, followed by twists of realization, understanding and an epic light show conclusion that begs for cathedral acoustics. Listeners are strapped into this soulfully sung script that was penned over a 20-year timeframe. Arranged and performed by veteran music artist Robert Richardson, Cell15 will remind listeners of Transatlantic, Genesis and IQ, but its classic rock influences and meaningful vocals would also entice any Kansas or Queen fan.” 

2015 was the year of forming the full time band to promote Cell15. After many auditions, a lineup of accomplished musicians was established, including Shane Jones on guitar, former Elephants of Scotland member Dan MacDonald on bass, Circuline's Andrew Colyer on keyboards and Bill Brasso on drums. A musical bond was formed to pursue recording more progressive rock music with a killer show sure to excite any audience.

In October of 2017, Cell15 played the inaugural year of the ProgStock Festival in Rahway, NJ, in addition to a show at the NJ Proghouse in June 2017. 

In 2018, a modified lineup of Cell15 played the 15th Annual RoSFest (Rites of Spring Festival) in Gettysburg, PA, with Bob Richardson on vocals, drums, and keys, Dan McDonald on bass, Andrew Colyer on keys, Shane Jones on guitar, and Ornan McLean as a guest drummer.

Prog Rock fans may be few but they are the most loyal and appreciative group of people who love the complexities of composition. Prog is the “Classical” music of today and will still be loved long after “Pop” music is forgotten.
