Mackenzie and Band continue stretch of opening for Country Music's Hottest and Most Iconic Acts in 2022 and 2023!

Mackenzie and her band continue to open for country music's hottest and most iconic names.  The band played opener in 2022 for Ryan Hurd outside of Wrigley Field in Chicago in a show sponsored by Budweiser, The Chicago Cubs, and country station US99.  Ryan, who perhaps is best known as the husband of Maren Morris, wrote #1 songs for Blake Shelton, Lady A, and Luke Bryan.  Ryan is signed to RCA Nashville Records.  Mackenzie and the band followed that with an August show opening for country superstars Lonestar.  Lonestar dominated country charts in the 1990s with numerous #1s and songs that had an impact well beyond country music.   

     To kick off the 2023 season, Mackenzie featured songs from her upcoming album "Quarter Life Crisis" while opening for breakout Country artist Kylie Morgan in Chicago in a sold out show!  Kylie had been featured at the CMAs and her online streams have surpassed the 100 million mark over the last year!

     In June 2023, Mackenzie opened for the 2006 CMA vocalist of the year Rodney Atkins to a packed house of over 5,000 fans in a show hosted by The Village of Antioch and Country Station US 99!  Rodney had a stretch of six number one country songs between 2006 and 2011.  Rodney has been nominated for a CMA award six times and in 2006 won the CMA for top male vocalist!  Mackenzie and her band opened with a 65 minute set!

     Other notables Mackenzie has opened for include Chris Janson, Jordan Davis, Lee Brice, Parker McCollom, The Vandoliers, and Mike and the Moonpies.  (Photos: Ryan and Mackenzie pictured outside of Wrigley Field, Mackenzie and Kylie backstage in Chicago, Mackenzie and Lonestar pictured in the green room at The Vixen, Mackenzie pictured on stage outside of Wrigley Field!

Mackenzie and The Band:  Festivals, Town Concerts and Album Release in 2023

     Mackenzie and her band hit the festival circuit hard in 2022 and 2023 with appearances at fest.s in four states and multiple trips to Country Thunder Wisconsin!  They balanced that with town concerts throughout Northern Illinois and a few preferred indoor venues in Illinois, Wisconsin, Michigan and Indiana. 

    Mackenzie and her Nashville team released her latest and most ambitious project yet when her album "Quarter Life Crisis" began dropping songs in July of 2023.  "Gone Before I Got Here" was the first release and received over 100,000 Spotify streams after only 8 days online!  Song number two "Mean Girl" was released on September 13th and hit 100,000 streams after one month on the market.  The third song "Sugar Daddy Issues" will be released in January of 2024 as the marketing team decided to slow the release to develop a more targeted and faterher reaching marketing plan.

About Mackenzie O'Brien Songwriter

Mackenzie was given the nickname "Hummingbird" at an early age as she was often found playing alone and humming made up melodies.  The name stuck and the hummingbird has become a symbol for her band and brand.  She released a song and music video entitled "Hummingbird" in 2020.  Link to song:

Mackenzie reports knowing from around the age of four that music was her calling.  At the age of 14 Mackenzie picked up a guitar and taught herself to play chords very quickly while watching videos on youtube.  She stated that it was like part of her brain was unlocked and she again found herself linked with music!  

Mackenzie developed her skills on guitar, and some banjo, and began singing in bars and coffee houses upon graduation from high school.  She also hit open mic.s in the area, In Austin Texas, and in Nashville Tennessee where she built up music alliances and eventual partnerships.  Mackenzie recorded and released her first original song "It's Just a Line" in 2017 recorded at Nashville's iconic Omnisound Studios!  The song solo written in a singer songwriter style was featured on the Iceman's Nashville based radio show for up and coming original artists in that same year.  The song is no longer on online listening platforms but can be found at the following link...

Link to Song:

Mackenzie continued performing in Chicagoland and In Wisconsin and continued developing her writing style while being known for her development of song melodies.  Mackenzie was sought out by various writers and built songwriting partnerships in Nashville and online with other writers across the US and Canada.  In 2019 Mackenzie won a songwriting contest sponsored by Merf Music Nashville which put her path on a new trajectory.  To date, Mackenzie has written with Grammy nominated and Grammy winning writers, writers that were BMIs top money earners, and many writers with #1 songs to their credit.  

At this time, Mackenzie continues to write with a team of writers in Nashville and she is excited about releasing her newest album in 2023!  The album will feature a more americana music blend and one song (Sugar Daddy Issues) that is completely outside of the "Nashville Box".  Her music can be found on all the online listening platforms.
