i.O. Underground set to release new EP on July 22, The Underside


Emerging independent Colorado-based rock trio i.O. Underground will be releasing their sophomore EP, The Underside EP, on July 22. The Underside features the group’s latest singles “What U Do” (PRESS HERE to listen/watch the official lyric video) and “Wall” (PRESS HERE to listen/watch the official music video).

i.O. Underground first introduced the new 6-song collection at the beginning of May with the release of “Wall. Shimmering keys and ebullient guitars ignite the track’s momentum, which culminates in a chantable chorus punctuated by lead vocalist Grayson’s dynamic vocal delivery of “Got my back against the wall. Pushing hard, but I’m not falling down.” On “What U Do,” just released May 26, siren squeals beam out like an extraterrestrial buzz over a skittering beat as bass-y synths warble before climaxing on a guitar-charged refrain. Elsewhere on The Underside EP is the uplifting anthem “Once In A Lifetime, where a carpe diem chorus takes flight as a piano-laden bridge entrances, and “A Million Miles, which illuminates the idiosyncrasies of the group’s musical alchemy. Gentle guitar harmonics glisten between the glitchy production as the vocals expand from intimate verses into an infectious refrain, striking a perfect balance.

Anything goes for i.O. Underground, who erase restrictions and embrace creative freedom in its purest form. The three-piece – Grayson (lead vocals, guitar, bass), Casey Kannenberg (guitar, keys, bass, vocals) and Beau Harding (drums, vocals) – present a multi-dimensional signature style layered with future-facing alternative experimentation, singer-songwriter eloquence, and nineties-style rock energy. With influences as diverse as ColdplayMuse, and The Beatles, the group debuted their signature sound in 2020 with The Wonderside EP. The 6-song collection, highlighted by Save Me,” “Coming Apart” and Powers,” and live shows throughout the Denver/Boulder area has built i.O. Underground a quiet buzz and a growing fan base. They continue to push boundaries in 2022 with The Underside EP, which they hope makes a personal connection through a universally intriguing sound.
