Has School of Rock professor Jack Black turned his back against rock n roll for country music?

Jack sang the traditional country tune “Old Joe Clark” on his dad-in-law’s Grammy-nominated album “Rambling Boy”

“I wasn’t sure what to expect because I haven’t recorded or really sung any old songs like that before, bluegrass style, but it came very naturally and I cranked it out in two takes,” said Black.

This would certainly be interesting. Hopefully he releases his own Tenacious D country album and give chart-toppers like Taylor Swift and Carrie Underwood some much needed competition.

The 42nd annual awards show served as the Brad Paisley’s coming out party country’s jack-of-all-trades. The singer/guitarist had four nominations and won two awards, he repeated his 2007 victory as male vocalist and video. He opened the show with the song Start a Band, a duet in which he and Keith Urban pay homage to classic rock songs with quotes from them. And he co-hosted with Carrie Underwood who was also a winner with her third straight female-vocalist award.

Kenny Chesney won the big one, entertainer of the year, for the third straight year and fourth overall. George Strait became the Country Music Association’s all-time champ Wednesday night in Nashville when he picked up four CMA Awards to bring his career total to 22. Sugarland picked up its second straight duo award, and singer Jennifer Nettles won best song for writing Stay. Alison Krauss collected her ninth trophy and Robert Plant his first, as Gone, Gone, Gone won musical event. Lady Antebellum won new artist and Rascal Flatts won its sixth straight group award.

Overall a very entertaining night and a great one for country music.

A small study shows that listening to happy music, especially country, may help with your bloodflow, which results in a healthy heart.

In the study, 10 subjects were ask to choose their happy music and songs that can induce anxiety. Majority of the subjects chose country artists such as Hal Ketchum and Dwight Yoakam, to make themselves feel happy, as well as music from the “Footloose” soundtrack.

Participants chose hard rock bands such as System of a Down and Disturbed to induce feelings of anxiety.

On average, listening to the happy songs caused an increase in bloodflow due to the opening of the blood vessels caused by the release of endorphins or “happy chemicals” that are in the brain.

The study also shows that laughing can cause a 19 percent increase in the dilation of the blood vessel.

On the sad side, listening to somber music causes a 6 percent narrowing of the vessels.

So next time you’re in the record store, don’t forget to pick up a new Garth Brooks CD. It’s good for the heart!
