 Their festival gigs have included Austin City Limits, Chicago Blues Fest, Minneapolis State Fair and Old Settler's Music Fest.In September, 2019 they performed at Crossroads Village at Eric Clapton's Crossroads Guitar Festival in Dallas.The "Minneapolis Star Tribune" described a Peterson Brothers festival set "like a NASCAR race" with a "crescendoing jam through the Dramatics’ "What You See Is What You Get" or the version of Al Green’s "Take Me to the River" that sounded like it originated on Stevie Wonder’s "Innervisions" — all with Glenn soloing on guitar with the same flashy but fulfilling approach as their recent tourmate Gary Clark Jr."

In addition to Gary Clark, Jr., who The Peterson Brothers performed "Come Together" with at the 2019 Austin City Limits Festival, they have opened for and played with Robert Randolph and the Family Band, Kenny Wayne Shepherd, Buddy Guy and B.B.
