Solange's love for the music of yesteryear has been well-documented, and this weekend she brought that love to the stage at the Okechobee Music & Arts Festival in Florida.

At one point during her set, she brought out the Doobie Brothers' Michael McDonald to perform the group's classic "What a Fool Believes." The soul- singer also wrote about the moment on social media.

"Anyone who knows me knows that the Doobie Brothers are my musical/harmonic chord change hero's and that I listen to 'It Keeps you Running" everyday for encouragement," wrote the 30-year-old. "That was fun, Michael."

Next, Solange will be playing a slew of dates this spring, like in Portland at the Arlene Schnitzer Concert Hall on April 21. Then she'll be heading to Washington D.C.'s St. Elizabeth East Gateway Pavilion on May 6. Then from there, she'll be flying across the country to play at Arcosanti 2017 in Arizona on May 12 and 13.
