American/German/Swedish symphonic metallers KAMELOT were joined by Simone Simons (EPICA) and Fabio Lione (RHAPSODY OF FIRE) on stage during their July 15 concert at the Kavarna Rock festival in Kavarna, Bulgaria. Fan-filmed video footage of the performance can be seen below.

Simone — the longtime girlfriend of KAMELOT keyboardist Oliver Palotai — appeared on the song "The Haunting", which was included on KAMELOT's 2005 album "The Black Halo", and on the band's most recent ballad, "House On A Hill", as well the title track of KAMELOT's latest album, 2010's "Poetry For The Poisoned". She has also made a number of live appearances with the group, including on KAMELOT's South American and European tours.

Lione sang for KAMELOT on their North American, South American and European tours following the departure of KAMELOT's longtime frontman, Roy Khan.

KAMELOT's new album, "Silverthorn", will be released on October 26 (Germany), October 29 (rest of Europe) and October 30 (North America) via Steamhammer/SPV. The CD will mark the band's first release with new singer Tommy Karevik, the 30-year-old Swede who previously fronted SEVENTH WONDER (a group that he is still a member of).

In a brand new interview with RockLiveBG, KAMELOT keyboardist Oliver Palotai stated about the band's new vocalist, "[Tommy] was already with us on some tour dates as a guest singer, and he was singing on one or two songs. And in the past year, we were considering which singer to take. I was strongly on Tommy's side because he made a huge impression on me. Personality. of course. is really important. and he is a little bit introverted and I like this 'Scandinavian feel' about him and he fits KAMELOT really well."

He continued, "The final decision for him was sending in vocals, lyrics and recorded melody on a ballad that I wrote which is on the album. And it was so great and impressive. We all had goosebumps and when we heard that for the first time we knew immediately that was 'it.' He wrote most of the vocal melodies in the album also."

On the topic of the upcoming CD, Palotai said, "The cover was done by Stephan Heilemann. He also did covers for EPICA and my other band, SONS OF SEASONS. He is one of my best buddies, living in the neighborhood, and in my opinion, he is one of the greatest designers in the whole world. The amount of songs is ... I think 9 or 10 without the interludes. . . It's a concept album and it has a story. In the special edition you will get a little book where the story is described. All the songs will be around the story. It will be something like [2005's] 'The Black Halo'.

Regarding how the upcoming CD compares to 2010's "Poetry For The Poisoned", Oliver said, "To be honest, I'm not the biggest fan of 'Poetry For The Poisoned'. For me, 'The Black Halo' is a bit like a reference also when I produce bands in my studio. So we wanted to go back to 'The Black Halo' but also include modern elements, which we included since then. You will never hear from a band, Our new record sucks,' but this record is a real killer and brings KAMELOT back on track. It is exactly what I wanted, and I'm really happy with it. I hope the fans will like it as well."

KAMELOT guitarist Thomas Youngblood previously stated about Karevik: "We had around 800 candidates for the vacant position, among them a number of really renowned musicians, and having to reject them really wasn't easy."

In KAMELOT's search for a new singer, Youngblood found YouTube to be an amazing tool. "I listened to a clip of a studio production featuring Tommy and have to confess that his performance really amazed me," he said. "His approach to melodies and themes suits KAMELOT perfectly, and during our European shows we had plenty of opportunity to find out what a great guy he is."

Tommy first appeared as one of the guest singers on KAMELOT's very successful 2011 Pandemonium World Tour.

Youngblood on the style and content of the forthcoming KAMELOT concept album: "The new songs sound more symphonic and melodic than our last two studio recordings. The material brings to mind albums such as 'Karma' (2001) and 'The Black Halo' (2005). In addition, this will be the best production that KAMELOT have ever delivered. Because while other acts tend to opt for low-budget productions due to the difficult market situation, we have gone the opposite way: the new album will be a real statement, in terms of our compositions as well as in terms of our sound."

KAMELOT will support Finnish/Swedish symphonic metallers NIGHTWISH on a North American tour in September and October.
