[3] Unlike usual the pop music that dominated the show, he chose to perform mainly metal and rock songs in the contest.

The songs for the album were written by a number of Finnish metal musicians and songwriters such as Janne Joutsenniemi (SubUrban Tribe, Stone), Jarkko Ahola (Teräsbetoni), Marko Hietala (Nightwish, Tarot), Timo Tolkki (Stratovarius) and Tony Kakko (Sonata Arctica), among others.

[5] The album was recorded with Tuomas Wäinölä (Kotipelto, Nylon Beat), Mikko Kosonen (Maija Vilkkumaa), Nino Laurenne (Thunderstone), Mirka Rantanen (Thunderstone), Mikko Kaakuriniemi (Kotipelto), Pasi Heikkilä (45 Degree Woman) and Janne Wirman (Children of Bodom).

Koivunen's album was one of the fastest selling records in Finnish music history, with over 10,000 copies sold in the first week of sales.

[10][11] The album has received predominantly very positive reviews from metal magazines and webzines around Finland, Europe and the US.

Beside the six members there are also some quest musicians featuring in the album, as percussionist Teho Majamäki, Indica singer Jonsu and Amine Benotmane from Acyl.

"...in general we wanted to keep the focus on clean vocals, even though Niko is back in the band.

Constantly conflicting schedules and a fading interest in touring by some members have made the band run at half-speed.

And, to be honest, the idea of starting something brand new after all this time has become very appealing...."[19] Beside Amoral, Ari has played also solo and duo shows among others with his previous bandmates, Erkka Korhonen and Luca Gargano.

Ari has joined the Raskasta Joulua (Heavy Christmas) – tour in Finland each year since 2007 (except 2017 for vocal cord infection) with a group of well known Finnish metal vocalists.

In autumn 2017, there was a premiere of the Finnish 70s retro rock musical Raparperitaivas,[25] where Ari plays one of the main roles.

In 2017 Ari founded together with Marko Hietala and JP Leppäluoto a new group called Powerless Trio.

The trio plays their own favorite classic metal and rock covers and are also entertaining the audience by telling personal stories related to the songs.

His strong and very distinctive voice impressed the panel of judges (Asko Kallonen, Nina Tapio and Jone Nikula) and he was passed through to the next round of the competition.

He was then granted a place in the semi-finals, which would allow the public to decide which contestants would make it into the live final rounds.

In his semi-final round, Koivunen received a massive public vote of 86%, thereby allowing him to breeze through to the live finals.

A resident of Lahti, Koivunen breezed into the finals after winning 86% of the public vote for his rendition of Billy Joel's Piano Man.

On the first of March 2007, Koivunen reserved himself a place in the second round of competition with his version of Deep Purple's Perfect Strangers.

Koivunen moved into the third round of competition on 8 March with his performance of the Iron Maiden classic The Evil That Men Do.

The fourth Idols final was held on 22 March, and Koivunen chose to sing, in keeping with the week's theme, two songs by his own idols, the Led Zeppelin hit Rock and Roll and Hunting High and Low by the Finnish metal band Stratovarius.

The judges, however, were not pleased with Koivunen's continuance of the heavy metal line, and gave him an unprecedented four negative reviews.

The fifth Idols final was held on 29 March, and Koivunen won over the judges completely with his version of the Broadcast ballad You Break My Heart.

For his second song, Koivunen sang the Finnish hit Sielut iskee tulta by the heavy metal band Kilpi.

With these performances, Koivunen made it to the Idols final which was held on 6 April 2007 in the Helsinki Ice Hall, where he defeated his fellow competitor Anna Abreu by gaining 57% of the public vote.

As his reward for winning Idols 2007, Koivunen received a recording contract with Sony BMG, and an advance payment of 30,000 Euros.
