Isaac O’Sullivan, also known by his recently adopted alter-ego, Letterbox Kid, is a 23-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 several sets at local Summer music festivals.
Since then, and with entry to the prestigious Cork School of Music, Isaac has improved drastically as a musician and artist studying under renowned musical minds such as former Van Morrison guitarist Johnny Scott & illustrious music producer 1000 Beasts. 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 started 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. Since then and with multiple successes in the gigging world, working with artists such as Houseplants and Arthur Valentine, the Letterbox Kid has released three new singles to great applause, garnering editorial playlist spots for his song ‘BUGATTI’ on A Breath Of Fresh Eire.
The Letterbox Kids’ next song, titled ‘Baby’ will be released on all major streaming platforms on April 28th. It was made in collaboration with Hausu Records’ main-stay Automatic Blue (similarly to ‘BUGATTI’) and is sure to ring in the Summer a couple days early. ‘Baby’ is a summertime bop laced with nostalgic samples, vintage drums and a laid-back yet enticing delivery & flow from the charismatic Letterbox Kid. ‘Baby’ is the second single from the Letterbox Kids’ upcoming EP titled ‘SUMMER-TIME TAPES’. It’s guaranteed to make a splash this Summer and be ringing in ears like the sound of waves in seashells for many Summers to come.
