Isaac O’Sullivan, also known by his recently adopted alter-ego, Letterbox Kid, is a 22 year old singer-songwriter, rapper, and producer hailing from Cork City. Originally from the Waterford side of the border, Isaac began his life in music with a concept album called ‘A Live’. Here, Isaac pessimistically questioned what it meant to live in society and the fabrics that held it together, as well as the mental hardships he reluctantly endured during his schooling years. After the release of this minimalist, part spoken word, part singer-songwriter acoustic expedition, Isaac organized a launch gig and sold tickets on foot in his local area. Soon after, Isaac performed two more sets at local Summer music festivals.
Since then, and with entry to the prestigious Cork School of Music and graduation with First Class Honors, Isaac has improved drastically as a musician and artist studying under renowned musical minds such as David Hayes, Karl Rooney & illustrious producer 1000Beasts. Throughout the pandemic Isaac worked rigorously on his debut EP, titled ‘Elegant For A Rogue & Skinny For A Bastard’, which was released on all major streaming platforms in November of 2021. The EP consists of trap beats, slurred bars and emotional highs as Isaac starts to find his home as the Letterbox Kid in an unusual mix of trap, rap, and soul, inspired by the likes of Jeff Buckley, Kanye West, King Krule, & Travis Scott to name a few. With a belated EP launch taking place in An Spailpin Fanach in Cork City on the 31st of March which filled the venue, and a debut on the grand stage of Cyprus Avenue on May 20th which garnished coverage from Golden-Plec, and a more recent support slot of the famous HousePlants, the Letterbox Kid aims to take advantage of his unique ability to blur a distinct presence of musicality and charisma with interesting melodic hooks and passionate live performances.
The Letterbox Kids’ next release, I Miss You, is ear-marked for October 21st. Here, the Letterbox Kid enters a new world of striking synths and dark cinematic soundscapes, as he creates a planet on which to delve his deepest and darkest emotions and all that comes with them. It will be a statement as his first release of 2022 and a benchmark of quality for all future releases, as we start to see the musical and artistic progression of the Letterbox Kid unfold before our very eyes.
