Mitch Polzak
The big guy from out West and larger than life energy (he’s also 6’5’) performer, guitarist, singer, banjoist, songwriter, composer, entertainer, musical historian and teacher Mitch Polzak wears his heart on his sleeve and his playing in his heart.
Polzak performs rockabilly and 60’s country music with the religious fervor of Jerry Lee Lewis and Johnny Cash and delivers a Honky Tonk ballad with the sincerity of Merle Haggard and Waylon Jennings. Mitch will bring a room to a fevered pitch of joyous energy on the dance floor and then tell you a story in a song like two old friends sitting at a kitchen table at midnight.
Fluent in the musical languages of Country, Rockabilly, Honky Tonk, The Bakersfield Sound, Surf, early Rock and Roll, Bluegrass, Cajun, Blues, and Truck Driving music gives Polzak the unique voice of the melting pot of the American musical experience.
His virtuosic guitar skills and influences range from the blazing flying fingers of Joe Maphis , Marty Stuart, Roy Clark, and Don Rich to the timeless dreamlike state of “Sleepwalk” by Santo and Johnny along with the vast valleys of deep rumbling twang reminiscent of Duane Eddy.
Polzak’s abundant joy in communicating with people through music leaps off the stage through every fiber of his being. His near-constant genuine smile can be seen clear across the room and invites you in without any pretense or judgements. Some call him “The Honky Tonk Mister Rogers”!
Loren O.
Loren is a musician and performer, known as “The Mayor of Music” in Livermore, CA. He performs a variety of genres, including Country-Western, Blues, Rock, Pop, and even Christmas tunes.
