Shay-Jean evolved from the successful creative collaborations that Seamus Dever and Jon Huertas have developed while starring in the ABC television show “Castle” for eight seasons. Their infectious chemistry has created one of the most endearing bro-mance partnerships on television. Shay-Jean features the alter egos of Seamus (Shay) and Jon (Jean) as a musical group that infuses 90’s influenced R&B, combined with eclectic hip hop, to create an electrifying sound that also harnesses their consummate chemistry and comedic tones that has endeared so many fans around the world. With the special release of their first single, “Definition of Love,” with the video featured exclusively on the Castle Season 7 DVD, this new project extends the dynamic duo’s successful partnership from on-screen into a new groovy and infectious musical collaboration. Their next single and music video will release in November 2015.
