'Madison Rising', a guitar-heavy group that bills itself as 'America's Most-Patriotic Rock Band' is now being call anything but patriotic after its horrific rendition of 'The National Anthem' at the Daytona International Speedway on Saturday.

Drivers can be seen chuckling during the performance, and websites across the country have called it everything from "awful" to "the worst rendition of The National Anthem ever." During a post-race interview, Driver Brad Keselowski said, "Well, I wish they would just sing the damn song."

See for yourself in the video below. It's brutal.

And while you're at it, check out some other botched versions of the anthem here.
