Rock On!!!

I first saw Pre-Existing at Universal Bar and Grill, and they were phenomenal! Guitar player Brad Boim blew us away with his Mr. Crowley guitar solo. Lead singer Kieran is the perfect frontman, with his classic-rock pipes and charisma. But truthfully, every member of this band is beyond talented. We loved them so much that we hired them to play at my birthday. And they are as professional as they are talented. Truly, GO SEE THIS BAND and/or HIRE THEM for your next event!! You will not be sorry.

Outstanding band — Delivered as expected, a fun night!

We booked Pre-Existing Condition for our company holiday party after a colleague recommended them, and they were absolutely fantastic from start to finish.

The band was extremely professional, easy to work with, and completely self-contained — they brought all their own equipment, handled setup and sound seamlessly, and made the entire process stress-free for us as planners.

Musically, they were a perfect fit for our crowd. Our team skews a bit older, and their 60s and 70s Classic Rock set (Zeppelin, Floyd, Sabbath, etc.) landed exactly right. They sounded great, played with energy and polish, and created a fun, upbeat atmosphere without being overpowering.

We also asked them at the last minute to help MC our Secret Santa gift exchange, and the singer Keron? (can't remember his name) did a fantastic job engaging the crowd, keeping things moving, and making it a genuinely fun part of the night. That kind of flexibility and willingness to help made a big difference.

Overall, they delivered great music, a great vibe, and a smooth, professional experience. I would absolutely book Pre-Existing Condition again and would highly recommend them to anyone looking for a reliable, fun, high-quality band for a private party or corporate event.

You're most welcome, Brent.
It was a pleasure and a honor to attend your holiday party and so much fun to play for you and your colleagues. There's nothing better for a musician than to play to a big room, filled with happy people who love what you're doing and that evening was a real standout for us. What a night!
Really appreciate the review and hope to see you all again soon.
Rock on!

What to expect

What to Expect

When you book Pre-Existing Condition, you’re not just hiring a band — you’re admitting a full-service Classic Rock treatment team to your event.

Musically:
Expect faithful, high-energy performances of 60s–70s (and early 80s) Classic Rock — Black Sabbath, Led Zeppelin, Pink Floyd, The Doors, AC/DC, Aerosmith, and similar legends — played by seasoned musicians who actually love this music and know how it’s supposed to feel. We bring the power, but we also bring the groove, dynamics, and restraint needed for private parties, corporate events, and upscale gatherings.

Volume Control Included.
We can be thunderous or tasteful — your choice. Backyard party? Ballroom? Private home? We tailor volume and intensity to your space and your crowd.

Professional & Easy to Work With:
• On-time arrival and efficient setup
• Clean, professional stage appearance (even under the lab coat)
• High-quality sound system suitable for most private events
• Flexible set lengths and pacing to fit your schedule
• Friendly, responsive communication before and during your event

Audience Experience:
Guests get a fun, nostalgic, high-energy rock experience without it feeling chaotic, amateur, or out of control. People sing along, dance, air-guitar, smile, and say “I forgot how much I loved this song.”

You Get Peace of Mind:
You get a reliable band that understands timing, crowd energy, and event flow — not just how to play loud.

In short:
We deliver the excitement of classic rock with the reliability of professionals.

No drama. No egos. No missed cues.
Just excellent music, happy guests, and a rock show that fits your event perfectly. 🩺🤘

About

Pre-Existing Condition is a four-piece Classic Rock cover band specializing in the medically-necessary administration of loud guitars, thunderous drums, and songs your doctor warned you about in 1978.

Formed by four lifelong rock patients with a shared diagnosis of “chronic riff dependency,” the band exists to keep the sacred texts of Black Sabbath, Led Zeppelin, Pink Floyd, The Doors, AC/DC, Aerosmith and their twisted cousins alive — and delivered at unsafe volume levels.

Kieron — Lead Vocals
Kieron is the attending physician of vocal damage, administering banshee-wail harmonics, blues grit, and soul-shaking screams with surgical precision. His job is to summon ghosts of rock legends and make them very uncomfortable. Side effects may include goosebumps, fist-pumping, and spontaneous air-guitar.

Brad — Lead Guitar
Brad is responsible for most of the injuries. His guitar tone is thick, loud, unapologetic, and possibly illegal in three states. He performs extended riff surgeries, solos with dangerous sustain levels, and has been known to resurrect Jimmy Page using nothing but a Les Paul and questionable ethics.

Pierre — Bass & Keys
Pierre handles the low-frequency heartbeats and atmospheric hallucinations. On bass, he rattles internal organs. On keys, he creates the haunted spaceships, dark cathedrals, and psychedelic fog banks required for proper Floydian treatment.

Mitch — Drums
Mitch is the blunt-force trauma department. He does not tap. He detonates. He keeps the entire operation alive with massive grooves, iron timing, and fills that feel like falling down a staircase made of toms.

Together, Pre-Existing Condition exists to bring the golden age of rock back into living rooms, backyard parties, corporate events, and any other venue brave enough to host them. We are equal parts nostalgia, adrenaline, and sonic malpractice — serving only the finest vintage riffs with modern volume and zero apologies.

If you grew up on vinyl, cassette, FM radio, or questionable concert bootlegs, this is your prescription.

No refunds. No soft rock. No smooth jazz.

Just the good stuff. 🩺🤘

Additional booking notes

Pre-Existing Condition is largely self-contained and easy to accommodate.

We Provide:
• Full professional PA system suitable for most private events
• All band backline (amps, drums, instruments, stands, etc.)
• Standard stage lighting if needed (optional — please ask)
• Our own setup and teardown crew (the band 😄)

What We Need From You:
• Power: Access to standard, reliable electrical power near the performance area (2–3 standard 120V outlets preferred)
• Cover for Outdoor Events: If the event is outdoors, the band must be fully covered (tent, canopy, pavilion, or stage roof) to protect equipment from sun, wind, and especially rain
• Performance Space: A reasonably flat, stable area for a 4-piece band and PA (approx. 10’ x 12’ minimum)

Sound Considerations:
We manage our own sound levels and can adjust volume to suit your venue, neighborhood, or event style.

Weather Policy:
For outdoor events, performance is contingent on safe weather conditions and adequate shelter for the band and equipment.

In short:
Give us power, a dry place to play, and enough room to operate — we’ll handle the rest.

No complicated riders. No diva requests. No fog machines (unless you really want one). 🩺🤘
