On 13 March 2020, Chronixx released the first single "Dela Move" from his upcoming second album, "Dela Splash". The title of the track and album were inspired by his hometown – De La Vega City, a district in Spanish Town, Jamaica. Despite the anticipation, the album was never released.
Chronixx maintained a low public profile between 2020 and 2025, releasing little solo material and making few public appearances. His absence from the mainstream reggae scene during this period led to widespread speculation among fans and media. While the reasons for his silence were never formally addressed, it was widely believed that he was focusing on personal growth and artistic exploration. His final solo release before this extended hiatus was the single “Never Give Up,” released in 2022.
While not releasing solo work during this period, Chronixx remained creatively active behind the scenes. In October 2020, he appeared as a featured artist on the track “Dark Horse” from Sa‑Roc’s album The Sharecropper’s Daughter. He also provided uncredited vocals on “Unstoppable”https://www.youtube.com/watch?v=Uh3Ab39DagM from Daniel Caesar’s album Never Enough (2023), "Reason" from Cleo Sol's album Gold (2023), and on “Tequan” from Smino’s album Maybe in Nirvana (2024), alongside Ravyn Lenae. Though uncredited, his vocal presence on these tracks was widely recognised by fans and music critics alike, reinforcing his continued relevance during his time away from the spotlight.
In addition to these collaborations, he made substantial contributions as a composer, lyricist, and songwriter on several albums by the UK-based collective Sault, including Earth, Today & Tomorrow, Untitled (God), 11, Acts of Faith, and 10. On 10, he is also credited with horn and guitar performances.
Chronixx made a few brief, impromptu appearances during this time. Notable moments include surprise performances at Protoje’s Lost in Time Festival in 2023, and the second annual Jo-Mersa Marley Birthday Celebration in 2025, both held in Jamaica. He also made a handful of rare live appearances around the island, maintaining a quiet presence in the reggae scene.
On August 3, 2025, Chronixx made a significant return to the stage as the main headliner of Reggaeland, a two-day festival held at the Milton Keynes National Bowl. He closed out the event with a powerful performance, marking his first major public appearance in several years. During this set, he announced plans to release a new album titled Exile later that year.
Philanthropy and Education Initiatives In July 2022, Chronixx and his team launched the JamCoders Summer Camp, a fully funded, four-week residential programme in algorithms and computer programming for academically strong Jamaican high school students in Forms 3–5 (Grades 9–11). Hosted at the University of the West Indies, Mona in Kingston, Jamaica, the camp is modelled after the AddisCoder programme in Ethiopia and offers free accommodation, meals, and daily instruction from lecturers and teaching assistants from institutions such as Harvard University, the University of California, Berkeley, and the University of the West Indies.
The JamCoders syllabus covers topics including algorithms, discrete mathematics, and coding, and incorporates project-based learning and educational excursions to encourage practical application of concepts. The camp accepts students from across Jamaica through a competitive application process, and participants are selected based on academic performance, problem-solving ability, and interest in technology.
Since its inception, JamCoders has graduated over 150 students representing all 14 parishes of Jamaica. Alumni have gone on to pursue further studies in computer science, engineering, and related fields. The initiative is funded through Chronixx’s Caring Hands of Rastafari (CHOR) Foundation, with additional sponsorship from the NCB Foundation, Digicel Foundation, JPS Foundation, JMMB Group, Grid Dynamics, D.E. Shaw, and other partners. Chronixx has stated that the camp aims to give young Jamaicans access to advanced technical education, bridge the digital skills gap, and inspire them to contribute to the country’s technology sector.
