Nestled in the heart of Denver, where the air is thin and the music scene is thick, Grey Madderz has been turning up the volume and dialing up the fun for over a decade with our unique mix of party rock favorites. We're one part rock legends, one part party enthusiasts, and a generous dash of "Did they really just do that song?" - yep, that's us!

.

We're the kind of band that believes a good show should leave you thrilled and a little breathless -I mean, hey man, it's Colorado!  Our musical journey is peppered with moments that are as  varied as our playlist. From entertaining an audience of rowdy bikers with the smoothest grooves to transforming the streets into an impromptu disco dance floor, we've got it all. And we do it because we believe life's too short for boring music.

Grey Madderz is more than a band; we're a musical ball of energy, spinning out laughter, surprises and sprinkle of madness. We're here to prove that live music can be the best kind of party, especially when they're infused with a little Denver-style spunk.

​

So, if you're ready for a good time where the tunes are catchy, the laughs are plenty, and the memories are unforgettable (and slightly unbelievable), you're in the right place. Welcome to Grey Madderz - where the music's loud, the vibes are high, and the only rule is to expect the unexpected. Let's rock this party together!
