Formed in 2015 in Chicago's DIY scene, their first two releases came through underground label Grandpa Bay (Water From Your Eyes, Mykele Deville, This Is Lorelei). Their subsequent 2016 EP “Imaginary Friends” weaved in experimental elements while showcasing a more complex instrumentation.

Over the next two years, the project slowly grew to over ten collaborators, culminating in their second full-length “Wonder Under” released via Midwest Action in 2018. The record was featured on multiple online publications, local magazines and radio outlets.

​Behind the production of founding member Mabel Gladly, their new sound fuses art rock, new wave, experimental jazz, krautrock, disco, funk and soul, thus creating their original blend of psychedelic orchestral synth pop. While joined by many collaborators on their studio projects, Glad Rags keeps their live shows raw with high-energy interpretations of their songs featuring the five core members.

​Their debut LP 'ALL OF THEM' is a sixteen track concept album released in 2021. It has since been featured in Bandcamp, BUST magazine, Chicago Reader, and Chicago Tribune, leading to a thirty date tour through 2023 across the U.S. and Canada. They are finalizing several smaller albums at their home studio Sinkhole Sounds, including sessions with Eddie Ashworth (Sublime, Izzy Stradlin) at the legendary Oxide Shed in Athens, Ohio.

The collective features some of Chicago’s top musicians who perform with acts such as J. Cole, SUPERFUND, Animal Farm, Jovan Landry, and with Moulin Rouge.

They have performed with Sen Morimoto, Hop Along, !!! (chk chk chk), Nnamdï, Speedy Ortiz, Post Animal, The Oh My's, Mykele Deville, Sloppy Jane, The Ophelias, The Beths, ONO, Emily Blue, Tasha, White Mystery, GIRL K, Andrew Sa, Jude Shuma, No Men, OTNES, GRLwood, + Resavoir.
