Tonight's all-new episode of Castle will take us on a wild ride into the life (and death) of a rock and roller named James Swan. When the musician winds up dead, a documentary film crew that was following him turns the cameras on Castle and Beckett, capturing the shocking details of their murder investigation.

But that's not all they capture …

According to Castle star Jon Huertas, the crew catches his character in his element — with a microphone in his hand and a song in his heart. That's right, guys. The 12th precinct's resident rocker is none other than Detective Javier Esposito!

"They allowed me to actually sing in the episode on camera in front of everybody. It's a lot of fun. You're going to love it!" Jon told Wetpaint Entertainment in an exclusive interview.

Fingers crossed he does a little ditty for medical examiner Lanie Parish!
