We learned this week that Nicky Romero and Avicii has been both collaborators and friends. They were even working together and still sharing files. They had last spoken about a month before the 28-year-old producer, Avicii, was found dead, but Romero must have been moved to finish some of those open sessions as a means to honor his “I Could Be the One” co-creator.

He dedicated a new song to his fallen friend during a recent set at Kingsland Festival in Amsterdam. The track is called “Heaven,” and it sounds like it features vocals from Coldplay’s Chris Martin who was Avicii’s favorite band and lead singer. “Heaven” is a big, bold anthem with a cheerful melody in line with Avicii’s style. The crowd reacts positively in a fan-made video, holding lights up in the sky.

It is sad to think about and imagine what it might have sounded like if Avicii were able to finish the song with Romero in the studio.
