"Hopprock" is the second taster of Sound Ancestors following last month's lead single "Road Of The Lonely Ones", and was edited, arranged and mastered by Four Tet.

Sound Ancestors will be released under Madlib's name, but Four Tet, real name Kieran Hebden, arranged, edited, and manipulated the tracks.

Hebden wrote on Instagram about the album last month, "A few months ago I completed work on an album with my friend Madlib that we’d been making for the last few years. He is always making loads of music in all sorts of styles and I was listening to some of his new beats and studio sessions when I had the idea that it would be great to hear some of these ideas made into a Madlib solo album. Not made into beats for vocalists to use but instead arranged into tracks that could all flow together in an album designed to be listened to start to finish."

"I put this concept to him when we were hanging out eating some nice food one day and we decided to work on this together with him sending me tracks, loops, ideas and experiments that I would arrange, edit, manipulate and combine," Four Tet continued. "I was sent hundreds of pieces of music over a couple of years stretch and during that time I put together this album with all the parts that fitted with my vision."

The new track arrives just days after Madlib's Madvillain collaborator MF DOOM was confirmed to have died. They released their debut collaborative album Madvillainy in 2004.

"Hopprock" is out now. Madlib's Sound Ancestors album is yet to get a release date, but is apparently due this month.
