It seems that UK pop legend Rod Stewart really will be “Forever Young,” thanks to the upcoming release of newly uncovered tracks from the artist’s catalog.

On September 29, a four-disc box set of Stewart’s studio rarities will become available as a box set (at $64.98) and a digital download (for $29.99). Featuring a meticulously-selected sample of songs spanning 25 years, The Rod Stewart Sessions 1971-1998 will feature alternate takes and early versions of both classic Stewart hits (“Tonight’s The Night (Gonna Be Alright),” “You Wear It Well”) and rarities, and even one previously-unheard track, the sequel to 1976’s “The Killing of Georgie” (“Innocent (The Killing of Georgie Part III)”). The set features both covers and original work alike. One unearthed track, a cover of the 1969 Python Lee Jackson song “In A Broken Dream,” features Pink Floyd’s David Gilmour and Led Zeppelin’s John Paul Jones.

Much of the music to be released in the box set derives from Stewart’s 1970s work, but producers Andy Zax and Cheryl Pawelski also ensured that Stewart’s entire career would be well-represented: Sessions draws from six of the musician’s albums from the 1980s, and the final disc in the box set centers solely around tracks from the 1990s.

Through Sessions, Zax and Pawelski hope to expose Stewart fans to different eras of the artist’s work. Says Zax, “Admirers of particular eras of Rod’s career may be surprised to discover, upon listening to this box, that there is far less difference between the Rod of 1971 and the Rod of 1998 – and all the years between them – than they had previously believed.”
