A Note From Our Founder

Before moving to Chicago, I spent several years living and performing in New Orleans—a city where music isn’t something you listen to, it’s something you live. It’s also where my family hails from, so my roots run deep there. The energy, spontaneity, and joy that define New Orleans music left a lasting impression on me, and I was determined to bring a little of that spirit to Chicago. I also brought with me a seemingly unrealistic amount of confidence that I could build a career around it.

I studied music in college and always knew I wanted to make a living doing what I loved. In fact, when I started this business, I told my mom that if I couldn’t make it work within a year, I’d go back to school and become an accountant. Fortunately, the music thing stuck. No offense to accountants—we need you, and your spreadsheets terrify me.

What began as a simple idea has grown into Sway Chicago, our flagship society event band, and the larger family of ensembles that make up Biossat Custom Productions. Along the way, I’ve had the privilege of performing with some of the most talented musicians imaginable and helping create celebrations for thousands of couples, families, organizations, and guests throughout Chicagoland and beyond.

What I learned from New Orleans—and from a lifetime spent on stage—is that music isn’t just entertainment. It’s how people celebrate, connect, and create memories. It’s the moment a packed dance floor erupts when the band plays the perfect song. It’s grandparents dancing alongside college friends. It’s the sing-along at the end of the night when nobody wants the party to be over.

That’s what inspires us every time we step on stage.

Our mission has always been simple: hire extraordinary musicians, treat every event like it’s the most important one we’ve ever played, and create an experience your guests will be talking about long after the last note. If your guests lose their voices from singing, your feet hurt from dancing, and your photographer captures a room full of joy, we’ve done our job.

Thank you for considering Sway for your celebration. We would be honored to help bring your vision to life and create a night you’ll never forget.

What We Believe About Live Music

A great band knows the room.

We play with you. Every set is a conversation, speeding up with energy, holding back when needed.

Every song deserves to be honored.

The dance you've waited for. The processional your grandmother chose. The anthem your friends scream. They're moments, not just songs.

Great events come from hard work.

Don't manage your band or night. The more invisible our prep, the more present you are. That's the point.

“Perfect From Start to
Finish”

Hillary Foreman, Google Reviews

Steve and Kurt were incredible throughout the entire process of planning our wedding & reception. We had a beautiful Beatles piano interlude during our ceremony, and CANNOT even describe how incredible the Sway Chicago team during our reception. We had their 10-piece option, and they truly made the night. Kept everyone on the dance floor, and doubled as a concert for many! Couldn't recommend them more. Thank you Sway Chicago!
“Unforgettable
Reception Energy”

Coreen Kiva, The knot

Sway Chicago was incredible and made our reception truly unforgettable. The dance floor was packed all night and our guests couldn’t stop complimenting how amazing the band was. Steve was also fantastic to work with from start to finish. Highly recommend!
“Beyond
our Expectations”

Sam B, The knot

I can't tell you how many times I heard from our wedding guests, "That was the best band I have ever heard at a wedding". Their voices were insane, the saxophone was stellar, and they really kept the party going without much direction from us at all! This is a smooth, fun, impressive, and kind group of people that will elevate your special day beyond what you can imagine. We can't thank you enough, Sway
“Simply the Best Choice”

Ariel B, Yelp

I would highly (highly) recommend Steve and the Sway band. They were absolutely amazing at the wedding itself, and great to work with beforehand. More specifically, their sound was amazing at the event, and they had range to cover many genre of music for different audiences. And they were very helpful on the front end, with respect to ideas and how to choreograph the entire event. In short, they were awesome in every respect!
“Kept the dance,
floor packed”

Shannon, Wedding Wire 

Absolutely amazing! Hiring Sway for our wedding was one of the best decisions we made. Their performance they kept the dance floor packed all night long. From classic hits to contemporary favorites, their set list was diverse and kept everyone entertained. Not only were they incredibly talented musicians, but their professionalism and enthusiasm were evident throughout the entire planning process. They were so great at being attuned to the vibe of the party and when to play an upbeat or more slow song to catch our breath. Sway truly elevated our special day and made it unforgettable. All of our guests were so impressed and had an amazing time. We can't thank them enough for creating such an incredible atmosphere
“Magnificent! Star
Rating!”

Paula , Wedding Wire

Sway was incredible! By far the best decision we made for our wedding. Aside from being incredibly easy and fun to work with, everyone was so talented and Steve was absolutely amazing. Every guest made a comment about the band and we are still getting compliments months later. I don't think anyone left the dance floor all night. We worked with Steve and made a playlist and our "must haves" and he did such an amazing job reading the room and making every song perfect. I highly recommend going to see them at the Drake. We can't wait to find an excuse to book them again! Thank you again, Steve, you really did make our wedding day PERFECT!
