The friendship between Mac DeMarco and Logic continues to grow as it is revealed the duo have a collaboration in the pipeline.

Earlier this year we reported the quite bizarre news that Logic, the rapper best known for his album his hip-hop records and mixtapes, took the decision to have DeMarco’s name tattooed on his body.

Now, as Logic reveals plans to release a novel called Supermarket, about “a guy falling in love with a girl,” he has also recruited DeMarco into the creative process.

The novel, out via Simon & Schuster next year, will come equipped with a soundtrack and, on that score which is full of “funky psych-rock guitars,” DeMarco has produced one of the tracks.

In an interview with Billboard, Logic offered his slight concern at having created a rock album to accompany his book. Despite his initial trepidation, his concerns were eased when singer songwriter John Mayer gave the record his seal of approval.
