Epik High have had plenty of ups and downs in their career since forming in 2003, when they struggled to attract public interest in their complex, lyrical rapping. That all changed with their 2005 breakthrough single, “Fly,” whose inspirational tone established the template for many of their subsequent hits. Despite their popularity, they've never shied away from tackling tough topics like religion and depression in their tracks. They keep pushing boundaries in their music as well, keeping up with the latest developments in hip-hop while never losing their signature sincerity and softness.
