Now age 77, Placido Domingo has spent the wealth of his life stirring souls and enflaming passions as the King of Opera. The Spanish tenor has performed hundreds of classic roles in all the esteemed opera houses of the world, from Tosca's Cavaradossi to his career-defining stint as Verdi's Otello. He has also achieved mainstream crossover success in Latin and pop music, with his multi-platinum records garnering fourteen Grammy and Latin Grammy Awards, and two Emmys to date.

Aretha Franklin's importance cannot not be overstated. She is simply one of the greatest singers the world has ever seen. With a voice which can't be mistaken, her mammoth back catalogue includes the classics Respect, Think and (You Make Me Feel Like) A Natural Woman. She was the first woman inducted into the Rock 'n' Roll Hall of Fame, has a star on the Hollywood Walk of Fame and even made a glorious cameo in The Blues Brothers.

If there was any justice in the world, John Prine would be a household name. Playing in the Chicago folk scene of the early 70s, Prine was plucked from obscurity by Kris Kristofferson, an endorsement which helped to land him his first recording contract. Bob Dylan is also one of his biggest fans, terming Prine's work "pure Proustian existentialism". He's a singer who trades in life's little details, imbuing everyday existence with a kind of romantic grandeur. Now in his 60s, Prine is still going strong. It may be a while since his last record but he always seems to be on the road. He tends to tour with a very sparse backing band, leaving his words front and centre, just as they should be.
