The Mackenzie O'Brien Band


The Mackenzie O'Brien Band was launched in 2018 as Mackenzie began to play larger venues apart from the smaller bars and coffee houses where she kicked off her solo (and duo) career.   Jeremy Witz (Jerry Wyld) (Lead Guitar) had already played over 100 shows with her at that time.  Dean Sinclair (Deanie Boy) was soon added on drums and Scott Gauger (Scottie G) joined the band a year later as the full time bassist and back up vocalist.  

In a short time period (made shorter by Covid) the band has defied odds by continuing to move ahead in spite of being a young band with a female lead.  Mackenzie's reputation had been growing and has continued to grow in Chicagoland as well as in Nashville Tennessee!  

The band has been recognized as one of Chicago's best Country bands and one of the only that can flip and play all original music.  To date, the band has played at county fairs, festivals. Country Thunder, and the band has opened for numerous country stars!  The band is also one of a few whereby all of it's members are full time career musicians!  

In the last year, the band has hosted guest musicians who have added banjo, mandolin, pedal steel, and dobro to the mix.  The band is currently available for bookings in Chicagoland, Wisconsin, the Midwest, Nashville Tennessee, and beyond.

Mackenzie O'Brien

Singer Songwriter, Band Leader, Performer


Mackenzie O'Brien is a singer songwriter and band leader from Northern Illinois.  Mackenzie was given the nickname hummingbird as a very young girl as she was often found playing alone and humming made up melodies.  This gift has stayed with Mackenzie to this day and she is a sought after melody driven songwriter!  To date, Mackenzie has landed several dozen songs on small market radio in the US and in Europe.  

Mackenzie continues to build her career with her band in Chicago and with songwriting partnerships around the US.   In December of 2019, Mackenzie entered into a relationship with Merf Music Nashville and in more recent months entered into another relationship with Daredevil Productions Nashville.  It is through these partnerships that the foundation is being laid for Mackenzie's next big project!  Mackenzie looks forward to sharing parts of this project in the early months of 2022!

As a band leader Mackenzie continues to build her band through the covering of more challenging songs, and through the delivery of more compelling original songs.  The band has played county fairs, local fests, Country Thunder, and top area venues like Skooters Roadhouse, The Hard Rock Casino, The Cubby Bear, Joe's On Weed Street, The Hideaway Brew Garden, and many many others.  

Mackenzie and her band have also opened up for country stars and received recognition from many VIPs in the industry.  Stars opened for include:  Chris Janson, The Vandoliers, Sam LLanas of the Bodeans, Parker McCollom, and Jordan Davis as well as a post concert played after Lee Brice's show!   John  Oates (Hall n Oates), Lee Ann Womack, Artie Kornfield (Former VP at Capitol and Woodstock Fest Founder), CB Head Talent producer at the Voice (NBC), and many others in the field have recognized Mackenzie's talent and commented on such. 

Mackenzie's hope is to build her brand, share new songs and create new partnerships that lead to music with a greater impact on those around her!   She is thrilled to have current partnerships with the companies mentioned above as well as with Breedlove Guitars, Carlino Guitar Straps, and The Moo Country Boutique in Leipers Fork Tennessee!


News and What's New

     Opening for Parker McCollom at Joe's on Weed

Chicago:  Thank you to Country Music Blogger Backstage Bobbi  (pictured) for interviewing me for her blog prior to my opening for Parker McCollom at Joe's on Weed.  There's a link to the interview under the pic of Bobbi and me.  Also, a big shout out to the staff at Joe's for making me and the band feel so welcome and for taking care of so many things I had not even thought of.   Also, Thank you to Dawn at Moo Country for shipping my outfit up from Tennessee in time for the show in Chicago and to Eddie Carlino for making me the coolest guitar strap for the show!  I am so blessed to know all of you and I'm humbled by your knidness!!!!!


                    Back to Nashville in January

Mackenzie will be in Nashville in January but this will mark her first trip to music city that will only include one public performance and no time in the studio.  Instead, Mackenzie will be working with eight teams of writers that include several past grammy nominees and one grammy winner.   These sessions will support Mackenzie's latest efforts to rebrand and move towards a more organic Country but also Americana style.   "I'm super thankful to Merf Music and Daredevil productions for making this happen and I'm grateful for the incredible opportunity they are giving me".  The results of these sessions as well as songs Mackenzie has written in the last year, will be considered for a project in the spring of 2022.
