Growing up near Austin
Both brothers were born in Austin and raised in nearby Bastrop, Texas. Alex began with violin at nine before taking up bass. Glenn started guitar at roughly eleven or twelve. Music soon replaced most of their other childhood activities.
A family operation
Their parents handled much of the work away from the stage. Their father drove them to performances and helped promote shows, while their mother assisted with bookings, social media and daily organization. The support was practical without dictating the brothers' creative decisions.
Discovering blues, funk and soul
The brothers studied B.B. King, the Isley Brothers, Earth, Wind & Fire, the Brothers Johnson and a wide range of rock music. Glenn was especially affected by footage of Jimi Hendrix at Woodstock, where technique and complete physical freedom appeared inseparable.
Learning to perform together
Glenn and Alex did not build separate careers and later form a duo. They learned their instruments while playing beside one another. Years of rehearsal created an ability to change direction onstage without stopping to explain the next move.
Comfort on stage
By their late teens, both musicians looked unusually settled in front of an audience. Repetition explained part of that confidence, but independence mattered too. Their family protected the project without controlling how the brothers moved, arranged songs or communicated onstage.
Education alongside touring
At the time of the interview, Alex was finishing high school while Glenn studied music business and audio engineering at Austin Community College. Production and recording were becoming increasingly important as the group worked on live material and new original songs.
Building an audience outside Austin
Regular appearances at Austin's Continental Club gave the duo a strong local base. They also wanted to reach more of Texas and tour nationally. Festival performances showed that their chemistry could translate beyond a familiar club audience.
A memorable San Antonio return
One early-2017 highlight was a show at Sam's Burger Joint in San Antonio. The brothers had not presented their own show there for some time and were uncertain about the turnout. The audience response confirmed that the music had travelled beyond their regular Austin crowd.
Original material and production
Live performance was the foundation, but recording offered a different challenge. Writing and producing original material gave the Peterson Brothers a way to carry their influences forward without becoming a museum version of blues.
Where the chemistry comes from
Their communication appears instinctive because it was built over years. Family support, shared listening and thousands of small musical decisions created a partnership in which each brother can anticipate the other's timing. That relationship remains the center of the band.
