Rock 'n Roll Team Building
multi-city
Connection. Creativity. Chaos (the fun kind). Available all over the USA!
Forget the icebreakers and trust falls. This is team building that cranks up the volume and gets your people actually connecting — not just collecting another tote bag.
We take your team, hand them a mic (sometimes literally), and turn a room of colleagues into a full-blown rock choir. It’s equal parts live music, laughter, storytelling, and spine-tingling harmony — all tailored to your event.
Here’s What You Get:
• 🎸 Live Music that kicks like a drum solo at Wembley
• 🎤 Storytelling that hits the heart (and the funny bone)
• 🎶 3-Part Harmony Choir — no singing skills required, just good vibes
• 🤘 Audience Improv — spontaneous, unforgettable, and never awkward
• 📝 Custom Song Creation that ties your event together with a chorus your team will hum all the way home
Perfect for:
• 🚀 Launching big ideas
• 🔋 Energizing the middle of a long agenda
• 🎉 Ending on a high that actually gets remembered
We’ve done this with 10 people. We’ve done it with 2,500. Either way, we bring the same stadium-worthy energy. We’re fronted by Grammy-nominated INXS frontman Ciaran Gribbin, backed by world-class musicians, and powered by pure rock ‘n roll spirit.
This isn’t “team building.” It’s a shared experience that gives your people goosebumps, grins, and genuine connection.
Ready to shake things up? Let’s talk.
"Best Team Building I've ever booked. Ciaran and the band were great." Arrow Electronics
"It was absolutely the best team event I have ever run or attended." Lamb Weston
"I can honestly say that Rock 'n Roll Team Building is the best event experience I have ever seen at a conference." Jazz Pharmaceuticals
