Already a 23-year-old guitar phenomenon, the Dan Auerbach-produced El Dorado further establishes Marcus King as an innovative songwriter and one of the most soulful voices of his generation. King's solo debut, El Dorado is a contemporary sonic exploration of classic rock, blues, southern R&B and country-soul where subtle acoustics and pedal steel shines bright alongside raucous electric guitars and blistering solos. Following their previous collaboration on the song "How Long," King and Auerbach co-wrote twelve songs for El Dorado in only three days in his Easy Eye Sound studio.

On working with Marcus, Dan stated, "Marcus is known by so many as a phenom guitar player, and rightfully so. He's regularly the best player in the room, hands down. I was equally blown away by the way he can sing – so effortless, so soulful, straight from the heart. He's a naturally gifted writer too, which was clear right away. Everything for him is so innate – that's why he can always go right to the heart of a song and connect in a deeper way. He's really one of a kind and I'm proud I got to work alongside him on this record."

Debut single "The Well" is a fuzzy, electric-blues masterpiece which rumbles down the highway like Marcus' jet black El Dorado. The song's lyrics reflect on hard work and hard times. "When you have a $70 check go bad, you know times are tough," Marcus recalled and added, "The Well for me symbolizes the source of all my influences. It is everything that has happened to me to make me the man I am today."

El Dorado was written with legendary writers including Paul Overstreet, Ronnie Bowman and Pat McLaughlin. Auerbach also enlisted revered studio musicians including, drummer Gene Chrisman and keyboard player Bobby Wood. Their renowned work as members of the American Sound Studio band included Dusty Springfield's "Son of a Preacher Man," Elvis Presley's, "Suspicious Minds," and hits by Bobby Womack, Joe Tex and many others.
