Tim Sweetwood, a booking agent for Masquerade Music Park in Atlanta, introduced the festival in 2013. The name comes from the song "Steam Engine" by My Morning Jacket, a band of which Sweetwood is a fan. Sweetwood founded the festival to fill a gap he saw in the Atlanta music scene, where preexisting festivals did not carry the types of artists that Shaky Knees now hosts. In an interview with the music magazine Consequence of Sound, Sweetwood stated that he envisioned Shaky Knees as a festival focused purely on music, as opposed to similar festivals like the Coachella Valley Music and Arts Festival, which has attractions other than musical acts. Going into the future, he says he wants to continue to develop the brand, but maintain the festival at a smaller size than other festivals like Bonnaroo and Coachella to ensure that all of the festival's attendees can enjoy the experience. The first installment of the festival was held over two days in mid-May; it took place in Historic Fourth Ward Park and Masquerade Music Park, drawing acts such as The Lumineers, Jim James, and Band of Horses. The festival sold out and drew around 9,000 attendees per day. In following years the festival has moved to different locations as it has continued to grow, but has remained within Atlanta. Sweetwood has stated that a goal of the festival is to remain within the city in a place that is accessible to both attendees that travel from afar and those who live locally. In its second year the festival moved to Atlantic Station, a neighborhood that was designed and redeveloped in 2005, and expanded to three days. 2015 saw the festival move to Central Park, expanding its capacity to around 40,000. In 2016 the festival moved to Centennial Olympic Park, where it remained in 2017. In 2018-19 it returned to Central Park.
Accolades

Sister Festivals
Over time the founders of Shaky Knees introduced similar festivals exploring different genres of music.
Shaky Boots Music Festival
In 2015, Sweetwood introduced Shaky Boots, a music festival centered around country music, because there was no major country music festival in Georgia. The festival took place over two days and included artists such as Blake Shelton, Brad Paisley, Dierks Bentley, Rascal Flatts, and Old Crow Medicine Show. The festival was the first major multiple-day country music festival to be held in the state of Georgia. The festival went on hiatus in 2016.
