It's been 16 years since the release of Queen's 'Made in Heaven,' the British rock band's last studio album of new material featuring lead singer Freddie Mercury, who died in November 1991.

But there is still some unreleased Mercury material in the Queen vaults, according to guitarist Brian May, who says he and drummer Roger Taylor are sifting through what remains of the classic lineup's demo recordings for an upcoming album.

That’s not the only new Queen project on the horizon: May and Taylor are plotting a sequel to the long-running London musical 'We Will Rock You,' which opened in May 2002.

"The songs are there," May told the Daily Star, "it's just a question of finding time to get the right production."

Speaking of productions, Queen will be part of the 2011 MTV European Music Awards ceremony in Belfast, Ireland, on Nov. 6. The singer-free band — which amicably parted ways with Bad Company frontman Paul Rodgers in 2009 and has since considered working with pop star Lady Gaga — will perform and receive the Global Icon award.
