"Knows" is the debut album from Texas guitarist and songwriter Mark Lettieri. Released in 2012, the all-instrumental record displays his bold, soulful playing and composition.

A prominent Dallas session musician in the soul and gospel arenas, Lettieri has worked with artists such as Erykah Badu, Kirk Franklin, Anthony Evans, and Myron Butler. He is also a member of jazz-fusion supergroup Snarky Puppy.

For fans of Jeff Beck, Wayne Krantz and Herbie Hancock, the eight tracks on "Knows" are a mix of quirky, progressive funk, rock and pop, complete with massive grooves and hooks.
