Kaos Theory

Formed in 2015, Kaos Theory is a rock band based in Springfield, Missouri. They are four musicians with many years of experience playing professionally throughout the Midwest.

Kaos Theory is:

    •    Jeff Kastner – Vocals, Guitar

    •    Josh Pool – Bass, Vocals

    •    Paul Hooker – Drums, Vocals

    •    John Depperschmidt – Keyboard, Guitar, Vocals

Because Kaos Theory includes four accomplished musicians who all can sing lead, their song list includes a much wider range of material than that of the typical “bar band”. Their diverse song list was selected for the purpose of entertaining the audience as opposed to just playing the same old “stand-by” material that every other band plays. Although the band does play many popular rock songs, they also play many “deeper cuts” from the 80’s and 90’s that the crowd will remember and enjoy.

The members of Kaos Theory have previously performed in multiple regional acts including What’s Next, IROC, Paralandra, Lipriddle, and No Parking. Basically, this band is a group of seasoned veterans who know what it takes to entertain a crowd. Their credits include opening spots for national touring acts: Hinder, Foghat, The Guess Who, Starship, Vince Neil, Dokken, Warrant, Molly Hatchet, The Romantics, Sawyer Brown, and Nazareth.

Kaos Theory owns their own sound and lighting equipment, so when you hire them, you get a turnkey package. Their sound system was specially designed for its flexibility to be able to both fill up the largest venue and also provide a bearable volume in a smaller room.

You will find that Kaos Theory is a group of professionals that realize that their purpose is to deliver a professional and entertaining show for the audience.
