9. Rob Benedict
If you don't know him by name, you'll certainly recognize as him as a perpetual "That Guy" on television, showing up as a series regular on everything from Felicity to Supernatural to Masters of Sex. Benedict is just an all-around nice dude in the mold of Paul Rudd. Band: Louden Swain With a style that recalls an impressively karaoked Zombies song with post-grunge vocal affectations, Louden Swain have been finding time to make well-crafted pop rock since the turn of the century. Though Louden Swain has been labeled an indie rock band, their mainstream influences, which include Pearl Jam, R.E.M., and Tom Petty, are easy to hear in their pretty straightforward rock discography. The band resides in Hollywood, features a card-carrying TV star, and routinely finds their way onto movie and television soundtracks, but they're the most down-to-earth group you could ever hope to meet. Benedict cashed in on his connection to long-running fantasy-drama series Supernatural by becoming the traveling band for the Supernatural conventions held across North America. https://www.youtube.com/watch?v=65pc9dyrfnc
