Knockout was a pop-punk band that was formed in Chicago, Illinois in January 1999. The members were Jeff Warren (guitar and vocals), Steve Jeanindes, (guitar) De'Mar Hamilton (drums) and TJ Minich. (bassist) The band produced two studio albums and two singles appearing on two separate compilation albums. (Those being Punk Goes Pop and A Different Shade of Green: A Green Day Tribute.)

They released a nine song album called Driven to Distraction in September 2001 releasing it on Mr. Good Records. After this release, they toured with local bands, the main one being 504plan.

Knockout was also the band who introduced Fall Out Boy to Sean O'Keefe who recorded and produced F.O.B’s first album, Take This To Your Grave.

All out through April, May, June and July of 2002, Searching For Solid Ground was recorded, but finally in October 2002, Knockout released their new album on Fearless Records “Searching For Solid Ground”.

In July 2002, Knockout lost one of their crucial members, TJ Minich, who left so he could pursue other projects. So, Knockout brought along another bassist, Chris Tag.

Once again Knockout toured extensively all around the US. As the months went by, there was inner quarrel between the band about the band and writing. But a bigger problem happened when Chris Tag decided to leave. So the band got someone called John Regan to fill in the bass for them. But this turned out useless because shortly after, De'Mar and John left the band. Jeff, with only half his band brought in his friend Spencer Johnson for bass and Mark Rhoades, who was the former drummer for a band called Starstruck.

But after all of the blood, sweat and tears pushed into the band, it turned out that the Burnout cover was going to be their last song as they called it quits in August 2003.
