Glenn Hughes, known as 'The Voice of Rock,' has collaborated with a multitude of world-class musicians since he first began making a name for himself as the bassist and lead singer for Trapeze in the early '70s. His journey has taken him through a stint as part of the MK III and MK IV Deep Purple lineups and more, including working with Tony Iommi, which even led to him taking the stage as one of two singers at Heaven and Hell's final show in salute to Ronnie James Dio.

When Hughes came to visit our studio, we discussed his time spent in Deep Purple as well as the band's recent induction into the Rock and Roll Hall of Fame. Moving forward, he talked about his brief tenure as Black Sabbath's frontman (with greater detail in our round of 'Wikipedia: Fact or Fiction?' with the legend below).

Originally intending to sing on Iommi's solo record, Seventh Star was released as "Black Sabbath Featuring Tony Iommi," but the duo went on to collaborate once again on the almost ill-fated DEP Sessions as well as Iommi's 2005 solo record Fused. In the video above, Hughes explains working on these recordings and how the mix-ups happened.

The Voice of Rock was also invited to take part in Heaven and Hell's last ever performance at the High Voltage festival in 2010 following the tragic death of Ronnie James Dio. Hughes joined then Masterplan singer Jorn Lande onstage and reminisced about the experience as well as a humorous story detailing how he first met Dio, hearing his voice before seeing the man with the golden set of pipes.

Watch Hughes explain heavy metal history and what it was like working with Iommi, if they'll work together again in the future and how he felt taking the stage in an emotional salute to Dio.

Glenn Hughes will be embarking on a solo tour starting Aug. 9, playing material from his entire career which includes Trapeze, Deep Purple, solo records, Black Country Communion and California Breed. A full list of stops can be found at our 2016 Guide to Rock + Metal Tours.
