Showco was established in 1970 by Jack Maxson and Rusty Brutsche, and Jack Calmes, and is known for helping to pioneer post Woodstock-era stadium rock shows by providing state-of-the-art sound equipment for famous acts beginning with Led Zeppelin, Three Dog Night and James Taylor.

The dynamics of live music and the power required to generate the sounds we hear at concerts today were almost unthinkable at that time.

The equipment was also built to handle rugged touring schedules, outdoor weather conditions and quick assembly and disassembly.

[1] Throughout the 1970's, Showco expanded its multi-discipline equipment and services to include stage lighting, set design and fabrication, special effects/lasers and disco sound systems.

Later forays into stage lighting led to the 1981 formation of sister company Vari-Lite, Inc.[1] Showco was acquired by Clair Brothers in late 2000.
