Glenn Hughes (born 21 August 1951) is an English musician, best known for playing bass and performing vocals in the hard rock band Trapeze and in the Mk.

He was reportedly uninterested in the Deep Purple job until some of the other members proposed that Paul Rodgers of Free be brought in as co-lead vocalist.

[4] Although the recruitment of Rodgers fell through, Hughes had now become interested in the "two-lead-singer thing", and David Coverdale was later hired as Deep Purple's lead vocalist.

[2] In 1982, he joined with ex-Pat Travers guitarist Pat Thrall to form Hughes/Thrall, and they released one self-titled album which went virtually unnoticed at the time.

Part of the reason for the album's obscurity was the inability to support it with a proper tour, due to both parties suffering from drug addiction.

While waiting for a break in Osbourne's career, Iommi decided to record a solo album and Hughes was brought in to provide the vocals.

Due to the aforementioned contractual obligations with the record company, the album was credited to Black Sabbath featuring Tony Iommi and released in 1986 to generally positive critical reviews.

During his tenure in Trapeze, he played a Fender Jazz Bass as well as a Rickenbacker 4001 on the Deep Purple albums Burn, Stormbringer, and Come Taste the Band.

Hughes then released Music for the Divine in 2006, which featured Red Hot Chili Peppers members Chad Smith and John Frusciante.

Live in Australia, an acoustic CD and companion DVD of a performance at Sydney's famous "Basement" club was released via Edel Records on 17 November 2007.

In 2009, Hughes formed Black Country Communion with Jason Bonham (drums), Joe Bonamassa (guitar) and Derek Sherinian (keyboards).

In July 2010, Hughes appeared as a guest vocalist (together with singer Jørn Lande) fronting Heaven & Hell at the High Voltage Rock Festival in London as a tribute to the late Ronnie James Dio.

The book, titled Deep Purple and Beyond: Scenes from the Life of a Rock Star, was co-written with author Joel McIver[10] and featured contributions by Tony Iommi, David Coverdale, Ozzy Osbourne, and Tom Morello, as well as a foreword by Lars Ulrich of Metallica.

[11] On 13 September 2012, Hughes and Derek Sherinian met Bako Sahakyan, the president of the breakaway Nagorno-Karabakh Republic and organised a concert in Stepanakert.

On 4 December the next single, "Holy Ground", which is also the title track of the forthcoming album, was released and was added to the Planet Rock 'A' playlist.

[citation needed] The next day drummer Deen Castronovo announced that he had left the band, due to a future back surgery.
