Dedicated to Corey Perez, a fan who was diagnosed with cancer, “Blue” was released on April 14, 2017. Bliss n Eso met up with Corey in late 2016 in the hospital to make him feel better, as talked about in the 2nd verse of the song.

Corey passed away in 2017 to his cancer. Before his death he wrote the following on Facebook:

Through my struggles with cancer I have always tried to inspire as many people as I could through positivity and strength. My body may soon be gone but I know that my soul and my legacy will live forever. My ashes will be placed with my grandfather and then, My two best mates, My Dad and my brother have chosen to spread some of my ashes at Patong beach in Thailand. This is a place that I hold deep in my heart and I know that my loved ones can always reach me there.
