Beyonce’s last album was packed with star-studded features from the likes of Jay Z, Frank Ocean, Timbaland, Pharrell and more. However, it could be argued that the most important contributions came from an unknown talent: Boots.

The elusive singer/songwriter/producer worked on more than half of the tracks, producing “Haunted,” “Heaven” and “Blue.”

It’s clear there’s a real creative chemistry between Bey and Boots. And that chemistry shows up again on “Dreams,” a just-released track from Boots featuring vocals from the Queen herself.

The smooth song is one of the tracks off Boots’ upcoming mixtape, WinterSpringSummerFall.

Boots worked on many tracks on BEYONCE. One of the songs he didn’t work on, however, was the album opener, “Pretty Hurts.” The song was produced by Ammo (who works with DJ Luke) and was written by Sia.

In a new interview with NYTimes, Sia mentions that Beyonce wasn’t the first one with the song. The track was sent to both Katy Perry and Rihanna. RiRi’s people passed, while the song just got lost in Katy’s email shuffle.
