CITY rock fans are in for a treat when not just one, but two popular power metal bands pay a visit to The Cathouse.

Record label mates The Ordeal, from Germany, and English rockers Knock Out Kaine will play a double header on Saturday as part of a whistle-stop UK tour promoting both bands' new albums.

The German quartet will be headlining.

Front man Oliver Oppermann said: "You'll never believe it but I've never been to the UK before.

"I'm really looking forward to going to all the cities we're visiting, and I'll enjoy Glasgow, I expect a lot of good experiences.

"There are some great bands we like from the UK like Saxon and Iron Maiden and Deep Purple, they've always been idols for me.

"We're excited about Knock Out Kaine supporting us, it will be good working together."

The Ordeal formed eight years ago in Hannover and are Oliver, Kai Reuter on guitar, 'Cyborg' Haines on bass and Michael Fromm on drums.

Oliver's background couldn't be anymore different to the world of rock'n'roll, he trained as a flamenco guitarist, alongside Spain's Paco Peña, regarded as one of the world's foremost traditional players.

"I learned in Rotterdam with Paco," Oliver said.

"It's a very different kind of music, but I grew up with heavy metal in the 70s and 80s and it's always been my passion.

"Flamenco actually has a lot of common elements with heavy metal, the harmonies are quite similar.

"The guitar is the main instrument in both genres and requires a very high level of playing."

The Ordeal released debut album, Kings Of Pain, to critical acclaim and have toured most of Europe and recently completed a tour of China earlier this year.

"We played at music festivals in Guangzhou and Beijing," said Oliver.

"It was fantastic, we had audiences of about 80,000 people.

"They treated us like important rock stars."

The band will preview tracks from their second album, Descent From Hell, in Glasgow, which is released on Monday October 29.

Knock Out Kaine will also be hoping to impress with tracks from their debut album, House of Sins.

The foursome, formed in Lincoln seven years ago, pride themselves on not being "X Factor style overnight successes".

They've previously supported Steven Adler, Guns n' Roses' original drummer's band, Adler's Appetite, and won Kerrang!'s Best Unsigned Live Act award back in 2008.

The band are brothers, front man Dean Foxx, 28 and Lee Byrne, 25, on bass, Jimmy Bohemian, also 25, on guitar and the baby of the group, 20-year-old Danny Krash on drums.

Lee cites classic rock acts such as Guns n' Roses', Motley Crue and AC:DC as their main influences, but they're also partial to a bit of country.

"It's a bit of a mixture to be honest and we also like a bit of jazz and soul," he said.

The boys are excited about debuting House of Sins to a live audience.

"It took us a long time to make," said Lee.

"It's been years in the making, we're going to play every song on the album at the live shows.
