Michael O'Neill is a musician from Brooklyn, NY. He is a graduate of Hampshire College, where he created a full-scale theatrical production of an original rock operetta as his thesis project. Thereafter he moved to Chicago where he formed the band Princess and became one of the organizers of Texas Ballroom, a DIY performance/event space and host to countless music and art events.
 
In 2006 he relocated to Brooklyn, NY where he soon became a member of The Ladybug Transistor. He has toured with the band from 2006-2011 and contributed to their final release, Clutching Stems (Merge Records, 2011).
 
In 2008, he was a founding member of the group MEN, a music/art collaborative project whose focus is the radical potential of dance music. The band released 2 full-length albums; Talk About Body (Iamsound, 2011) and Labor (Men Make Music, 2013) . MEN has performed extensively across the world including performances on 5 continents, festivals such as Coachella (USA) and Lovebox (UK) and internationally renowned art museums such as SF MOMA, New Museum (NY), Museo Tamayo (MX), Andy Warhol Museum and PS1.  
 
In 2013, Michael formed The Point with Sammy Tunis while spending a summer writing music in an oceanside barn on Mt. Desert Island, Maine.  In 2014, they released three EPs, culminating in their debut album Pretty Marsh, which was self-released in 2014.

In 2016, Michael joined the Kyle Forester band and continues to collaborate with him on all kinds of live band karaoke shennanigans!  He has also began performing with Nicole Schneit in her band,
Air Waves. 
 
In 2016, Michael began working on new music with Alexis Gideon.  Through a series of collaborative music made via email, a new project began to emerge and by 2017 a full-fledged Princess reunion was underway. Together they created  a concept video album, Out There,  which explores toxic masculinity and the role men ought to be playing during the current cultural reckoning of misogyny.  The world premiere of Out There took place at the Andy Warhol Museum on March 1, 2019 followed by 59 performances across the USA at institutions including the New Museum (NYC), MIT List Visual Arts Center,. Wexner Center for the Arts, DePaul Art Museum, and MCA San Diego.  

In 2018 he launched High Time - a rock n roll band paying tribute to the classic psychedelic music of the Grateful Dead.

At the same time, Michael reunited with JD Samson and together with Roddy Bottum created the band CRICKETS - an intentionally minimal punk art dance band.  CRICKETS began performing in 2019 and will release their debut album in the spring of 2020.

In 2020, Princess premiered @1minworld at The Andy Warhol Museum, presented as a virtual broadcast due to the Covid-19 pandemic. Simultaneously, @1minworld has been released on Instagram as a series of 15 distinct one-minute videos that take the platform’s constraints as a challenge to be reckoned with.   

In 2021, Michael joined Man on Man with Roddy Bottum and Joey Holman.
