His career trajectory was cut short however when he succumbed to a mysterious pain disorder that made it impossible for him to perform music, much less most physical activity. After three years of countless doctors' visits and incorrect diagnoses, it was determined that he suffered from "Central Sensitization Syndrome", a relatively new diagnosis where the brain can hardwire injuries, so it continues to send pain signals even after the body is healed. Stefan has used his platform to speak honestly about his chronic illness and hopes his story can inspire others to overcome whatever challenges they may be facing in their lives.
His much-lauded Thunderclap EP (released earlier this Summer) signaled his return to form, with All Things Go heralding, " Alexander is back and better than ever". The New Nine lauded the EP as "an emotional pop masterpiece that will get stuck in your head but also make you cry if you let it sneak up on you."
