'I walked in, I saw me' is the comment by Robert Plant himself on seeing Billy perform.
Billy had great success in the 80s and 90s with his own original bands, touring with Ozzy Osbourne, Roger Daltrey and Uriah Heep.
in fact it was Ozzy himself who suggested Billy take up lead vocal after hearing him sing at soundcheck on his 'No Rest for the Wicked' Tour.

Billy also sang Orchestral Zeppelin with the full 65 piece Auckland Philharmonia Orchestra in New Zealand after a world wide search for the right vocalist to front this fantastic project.

also the author of 2 books, which displays his sense of humour as he tells the story of how Letz Zep started from humble beginning on the London pub circuit, to performing on the biggest stages in the world.

In the 90's Billy also recorded with musicians such as Neil Murray - Whitesnake, Scott Gorham - Thin Lizzy and Don Airey - Deep Purple.

'Billy Kulke commands the stage like the king of the sun' St Avold - France.

The man is insane, the same lions mane as Robert Plant. He has also internalised the habitus of his idol like no other, just like the original, a lot of Eros, sometimes androgynous, sometime full of testosterone. He Lures the fans, he flirts, he hold the mic like it's his most valuable possession, he almost kisses it. Like a magician, he commands the stage.

Every gesture fits perfectly, every blink of the eye. Sometimes he drops the diva and a blissful smile sweeps his face.

The man is in his role, he can sing, no question, his voice is made for the music of the legendary Led Zeppelin. - Regine Beddeke
