Mark Lettieri is a guitarist, composer and producer from Fort Worth, TX. Proficient in a multitude of styles, he records and performs in virtually every genre of popular music with both independent and major-label artists. He also composes and produces original instrumental music under his own name.

Working in the Dallas/Fort Worth Metroplex's gospel and R&B scene led Lettieri to join jazz/world group Snarky Puppy in 2008. The now two-time GRAMMY Award-winning band tours and records constantly, having performed on all continents except Antarctica.

Aside from Snarky Puppy, Lettieri has spent time on the road with neo-soul icon Erykah Badu, gospel singer/actress Tamela Mann, and American Idol: Season 11 winner Phillip Phillips. He's also performed with a myriad of other artists, including Anthony Evans, Chrisette Michele, Myron Butler, N'dambi, Bilal, and even Pat Boone.

An in-demand session guitarist, recent work includes David Crosby, 50 Cent, Snoop Dogg, Eminem, Adam Levine, Kirk Franklin, Fred Hammond, Lalah Hathaway, Eric Roberson, Lecrae, Lupe Fiasco, Keyshia Cole, Xzibit, as well as numerous radio and television jingles. Lettieri is also a member of Team SKP, a production collective led by Grammy Award-winning producer Symbolyc One (Kanye West, Beyonce).

Since 2010, he has been a member of the house band for the Marcus & Joni Show, a morning talk/variety show broadcast in 200 countries on Daystar, a Christian cable network.

As a composer/bandleader, Lettieri has released three albums, Knows in 2011, Futurefun in 2013, and most recently, Spark and Echo in 2016 (Ropeadope Records). Through tours with Snarky Puppy and social media network shares, these records have created a sizable buzz among fans of instrumental music worldwide.
