“The Past Is Never Past” is a sentimental, bittersweet song by singer Andrea Revel, whose music is a blend of folk-pop with light, electronic beats. If her voice sounds familiar, that’s because she’s also the vocalist on the ReGenesis theme that opens each show, a song she also co-wrote. Also featured are the ethereal vocals and moody instrumentation of Kristy Thirsk on “Home For Angels”, definitely a musical highlight from the TV series.”
