Ernie Gammage, co-founder of both groups. During his career, Ernie has been in many hot Central Texas bands, including The Fabulous Chevelles, Ernie Sky and the K-Tels, Plum Nelly, and the NewMatics.

The unreleased Sonobeat recordings of the Country Nu-Notes were taped at South Austin's iconic Broken Spoke dance hall, which opened in November 1964. Ten years later, in 1974, Sonobeat owner Bill Josey Sr. was in the process of retrofitting an old stone church in Liberty Hill, Texas, to house Sonobeat's new recording studios, but when the opportunity arose to record the Country Nu-Notes, the studios weren't ready, so Bill hauled his recording equipment to the Broken Spoke, where the Nu-Notes were scheduled to perform on Sunday, February 24th. Johnny Lyon, who Bill had recorded in 1973 at Sonobeat's North Lamar studio in Austin, founded the Country Nu-Notes; the band still performs from time to time in Central Texas.

The First Cumberland Presbyterian's, at 6800 Woodrow in north Austin. Sonobeat used the church's auditorium, which also housed a full-sized basketball court and had booming acoustics, to record the basic tracks for Plymouth Rock's single and unreleased material by New Atlantis and the Ohio Express. To protect the basketball court floor, producers Bill Josey Sr. and Rim Kelley rolled out area rugs, on which the bands set up their amps and speaker boxes.

Willie Nelson. Don recorded Night Life for release as Sonobeat's third stereo single in 1967. In 1973, Sonobeat owner Bill Josey Sr. moved the Sonobeat studios to Liberty Hill, Texas, the small Central Texas town that hosted Willie Nelson's 1975 Fourth of July Picnic and concert.

"Blue Hole Sounds", named by Sonobeat owner Bill Josey Sr. in tribute to his favorite central Texas natural swimming "pool", also in Liberty Hill. "Blue Hole Sounds" occupied an old stone AME Church.

Composer Roy Headrick's album of original songs was recorded at Sonobeat's home studio in northeast Austin in 1967 but wasn't released until 1970. Sonobeat's composer demo albums were pressed in a limited quantity -- usually 100 to 200 copies -- and sent to national record label A&R executives in hopes of attracting a covery by a major recording star.

The Johnny Winter photos were taken by Austin's legendary Burton Wilson, who's made a career of photographing musicians who've helped create Austin's robust music scene. Burton's photos are collected into several great books, including his own Burton's Book of the Blues and Austin Music Scene: Through the Lens of Burton Wilson.

An Ampex 354, borrowed from KAZZ-FM, where Sonobeat owners Bill Josey Sr. and Rim Kelley (Bill Josey Jr.) worked as station manager and DJ, respectively.

Wildfire guitarist Randy Love is Beach Boy Mike Love's cousin. The eight song demo album Wildfire recorded at Sonobeat's Western Hills Drive studio in northwest Austin in 1970 stayed "in the can" for more than 35 years. The album finally was released by the band itself in 2006.

In 1969, Frieda Borth belted out a spectacular cover of Janis Joplin's bluesy Try as a member of Contraband in a demo tape recorded by Sonobeat for band manager Mike Lucas, and, in 1975, Frieda returned to Sonobeat to record several original tunes as a member of Austin Blues-Rockers. Frieda, who also played guitar, arrived in Austin in 1968 and attended the University of Texas.
