Future has done a deal with Slash's label Roadrunner Records to distribute the album.
The companies will create what they are calling a "FanPack" release, to include a 132-page special issue of Classic Rock, called 'Classic Rock Presents: Slash, along with the self-titled album'.
With high street record chains struggling to stay open, the deal sidesteps the problem of supermarkets only stocking the top 20 CDs, making the record available in 4,000 UK retailers.
It is the first time a record has been distributed this way and will be the available to UK fans before the album goes on sale as a standalone CD anywhere else.
Mark Palmer, managing director of Roadrunner Records UK, said: "While the past few years have seen the unrelenting rise of Classic Rock in a troubled magazine market, it has also witnessed the gradual disintegration of high street record retailers.
"By partnering with Future to release the Slash FanPack we are able to make widely-available a quality product for those consumers that have a real passion and interest not just in Slash's new music, but also every facet of his amazing career to date."
Roadrunner Records is also home to artists such as Nickelback and Slipknot.
