Cassö’s debut track “Prada” was originally created for house parties he played at while attending Swansea University. Despite only producing for eight months and having no experience performing outside university halls, “Prada” catapulted him to new heights. The track was a remix of “Ferrari Horses” by D-Block Europe featuring Raye, which Cassö reworked on his university laptop. After uploading it to SoundCloud, “Prada” quickly went viral, amassing over 11 million streams and 80,000 TikTok creations in just four months. This debut success marked an impressive achievement for the 20-year-old student, who managed to feature two global artists on his first release.
