The Knock Blockers combine their assorted ska influences including first wave, two-tone, and punk ska as well as other genres such as rockabilly and swing to come up with their skankabilly sound. They've opened for national acts such as Reverend Horton Heat, The Toasters, Voodoo Glow Skulls, Reel Big Fish, and Three Bad Jacks.

In November of 2017, they released their first EP, Rocket Surgery.

The Knock Blockers are Andy on bass, Courtney on keys, Paul on the drums, Phil on guitar, and the collective Loafer Brigade in the horn section (bone, sax, and trumpet). They formed in Colorado Springs in 2017.
