Listen closely to the soundtrack on Crossing Jordan, and you'll hear some of music history's finest players giving the drama its distinct tinge. Not only did we hear rock stars like Iggy Pop, country greats like Lucinda Williams and iconic songwriters like Bob Dylan, but we also heard virtuosos like jazz great Django Reinhardt. The show did not mess around when it came to its music.

And apparently, neither did the show's star Jill Hennessy. As Jordan Cavanaugh, Hennessy even performs songs on her own show, starting in the first season episode "Blue Christmas," where she covers the Pretenders' "2000 Miles."

On that song, her voice is thin and frail, with a lilt like Joni Mitchell, but on the show's soundtrack, you can also hear covers of Tom Waits' "You're Innocent When You Dream," where the singer explores a deeper range of her register. On that same disc, you can find a cover of Bob Dylan's "It's All Over Now, Baby Blue," too, and you can bet your favorite blues album that Hennessy sings it with attitude.

Although Hennessy's career began in acting, her fans know she's also an active musician whose music picked up even more once Crossing Jordan ended in 2007. She released both of her records once she had the time to record, Ghost in My Head in 2009 and I Do in 2015.

Luckily, if you've missed out on all this music, she's got lots of music videos posted to her website for fans to catch up. And, of course, watching Crossing Jordan, you'll see her pick up the guitar, her fingers flying on the fret like a natural.
