Mario Lalli (born on the 22nd February 1966) is an American musician and entrepreneur based in the California area. Active in the music scene since 1981, Lalli is considered to be a pioneering figure in the desert rock scene and often cited as The Godfather of Desert Rock. Along with establishing the generator parties of the early 1980s, Lalli's early bands in Across The River and Yawning Man were instrumental in shaping the desert rock sound. Along with the instrumental psychedelic surf that is Yawning Man, Lalli's musical sounds have stretched to freeform jazz and soul (The Sort Of Quartet), Stoner Rock (The Desert Sessions, The Green Monarchs), and a wide arrangement of other sounds.

Cousin of Larry Lalli, father of Olive Lalli and Dino Von Lalli.
