In a recent interview with New York's Q 104.3, Valensi revealed that the long-awaited album is in the process of being mixed.
Radio DJ Jonathan Clarke also asked the guitarist if he could announce "when or if the album might see release," to which Valensi replied, "When, I don't know. If -- I would say, it's a strong likelihood."
Although details about the project are still scarce, rumors that the Strokes were working on new material arose last July.
In an interview with Music Business Worldwide, Artist Group International President Marsha Vlasic revealed that the alternative-rock band was "coming with new music," adding that "having them back on the live music scene is exciting."
The Strokes released their fifth studio album, "Comedown Machine," in 2013. The full-length was followed a few years after by the 2016 LP, "Future Present Past."
More recently, Julian Casablancas and his bandmates debuted a new song, "The Adults Are Talking," last May at a benefit show in Los Angeles.
Currently back on the live circuit, The Strokes will headline Ohana Music Festival in Dana Point, California on September 27.
The band will also perform at the Barclays Center in Brooklyn, New York, for next New Year's Eve. The show was announced to make up for their canceled headlining set at Governors Ball music festival last June.
According to Brazilian newspaper Destak, The Strokes are also set to headline Lollapalooza's South American festivals next year, alongside Guns N' Roses.
