Mike Guldin picked up the guitar at 15. Rooted in the blues of Muddy Waters, Howlin’ Wolf, Willie Dixon, Albert Collins, and the three Kings, he also absorbed the fire of the Allman Brothers, Clapton, Stevie Ray and Jimmie Vaughan, and the swagger of the Rolling Stones. Soul and R&B giants—Sam & Dave, Booker T. & the MG’s, Al Green, and the Stax/Hi Records sound—left their mark as well, along with the Muscle Shoals grit of Lynyrd Skynyrd, The Outlaws, Delbert McClinton, and Lee Roy Parnell. The result is Guldin’s signature blend of stinging guitar, earthy vocals, and the high‑octane drive of his band Rollin’ & Tumblin’, a sound they proudly call “Good Ole Butt‑Shakin’ Music.”

Guldin and The Tumblers are two‑time finalists at the International Blues Challenge in Memphis. The lineup features Guldin on guitar and vocals, Tim Hooper on keys, Bill Sharrow on bass, and Billy Wear on drums. A seasoned road warrior, Guldin has shared stages with Sam Moore, Delbert McClinton, Levon Helm, EG Kight, Tab Benoit, Tommy Castro, Teresa James, The Nighthawks, Little Milton, Shemekia Copeland, Debbie Davies, Saffire—The Uppity Blues Women, Michael Hill, John Sebastian, and Jimmy Vivino.

His debut, Caught Between the Blues and a Heartache, arrived in 2003, followed by Roadhouse Rhythm in 2005. In 2019, he released Live at the Sellersville Theater. Nearly two decades after his debut, Guldin partnered with Bill Sharrow and Blue Heart Records for Tumblin’, a 13‑track set of originals featuring standout Philadelphia‑area artists including Kevin McKendree, James Pennebaker, Lewis Stephens, and Luis Mora.

In 2023, Guldin and Rollin’ & Tumblin’ returned with The Franklin Sessions on Blue Heart Records, a back‑to‑basics, organic recording featuring Kevin and Yates McKendree, James Pennebaker, David Santos, The McCrary Sisters, Mikey Junior, and the Philly Funk Horns—another vibrant chapter in Guldin’s ongoing blues journey.
