Sean Cunningham Nashville Sean Cunningham has never been afraid to evolve. Before reinventing himself with Whatever That Is — a wildly adventurous, self-produced solo album that blurs the boundaries between alternative, modern pop, indie rock, and lyric-driven Americana — the songwriter spent more than a decade in constant motion, releasing music with several different projects. There was Atlas, the career-launching band that took Cunningham all the way to New Zealand, where the group's chart-topping single "Crawl" set a new record for the longest-running Number 1 hit in Kiwi history. There was also The Cunning, the Led Zeppelin-influenced rock band that he formed after relocating to Nashville. All of that momentum leads Cunningham to his full-length solo debut, Whatever That Is, whose songs are every bit as diverse as the musician who created them. From acoustic tracks like "No Strings" to lushly layered anthems like "Habit," Whatever That Is unfolds like a rallying cry from a musical lifer who, having already experienced overnight success during the infancy of his career, remains willing to rebuild, reimagine, and rediscover himself over and over again.
