North Mississippi All-Stars are proof yet again that selling out is easy.

Their latest release, “Polaris,” shows that they’ve traded in their soulful, bluesy jams for mediocre pop melodies with cheesy lyrics.

With 12 tracks clocking in at a mere 45 minutes, “Polaris” is a far cry from their 10 track, 54 minute debut album “Shake Hands with Shorty.”

-Back in those days, the All-Stars would splice tracks, thus creating lengthy jams featuring the creativity of lead singer/guitarist Luther Dickinson. On “Polaris,” Dickinson’s skillful guitar solos are few and far between.

With the exception of “Never in all My Days” and the ending to the final track on the album, “Be So Glad,” it’s near impossible to find a blues note on this album.

From the first track, “Eyes,” a new, insipid sound is afoot. This doesn’t sound like a typical North Mississippi All-Stars album, both lyrically and musically. Parts of “Eyes” are empty, boring pieces that are more adult contemporary and less homegrown, Midwest blues.

Musical matters worsen once Dickinson’s younger brother Cody sings on the fifth track, “Otay.” Not only does he sing like an American Idol, but his lyrics (“Tell me what you’re all about/ Cut me in or cut it out/ It’s all good, otay.”) are a shameful display of what this band has become.

On first listen, this sounds like a line from the new John Mayer album. But upon further inspection, it’s just the empty sound of a talented band selling out.
