2002, where he also met Gommans. The tour brought the band to play at the important Graspop, Pinkpop and Dynamo festivals in Belgium and the Netherlands. The Pinkpop Festival performance on 30 May 2004, was televised for a Dutch TV station. The first leg of the tour culminated with the performance at the Wacken Open Air festival, on 7 August 2004. New dates of the tour were added at the end of the year, but some shows were cancelled when drummer André Borgman was admitted to a hospital and diagnosed with lung cancer at an initial stage. The official site of the band reported the news of Borgman’s illness and confirmed some shows, with Ayreon, Star One and Gorefest drummer Ed Warby standing-in for Borgman. The band spent the first half of 2005 concentrating on the material for the new album Remagine, while Borgman received intensive treatment to cure his cancer. Luckily, the cures were successful and Borgman was back behind his drum kit for the final leg of the Invisible Circles tour in South America in August 2005. Critical and commercial reception After the almost unanimous praise received by the album Decipher and the perplexities raised by the new musical direction of the EP Exordium, there were great expectations for the new album by fans and specialized press alike. The complexity of the music and concept of Invisible Circles produced mixed reviews, ranging from highest praise to complete failure, even in the same publication. The bold move of making a concept album about such a controversial matter was generally appreciated but, as Eduardo Rivadavia said in his AllMusic review, this could be a "slightly overambitious creation". The Maximum Metal reviewer states that "concept albums are always hard to pull off and not many bands can do it well" and "here is another failed attempt". It was the general opinion of most reviewers that Floor Jansen's lead vocals are at her best and "her performance here is powerful, dramatic and very impressive overall, no matter how she chooses to sing". However, her lyrics were sometimes considered a weak point of the album, despite the fact that the band "placed as much emphasis" on them "as they did on the music". Sam Grant of Sonic Cathedral Webzine considered them "trite" and "disappointing". In particular, the spoken dialogue by Somerville and Lansford was generally considered badly acted and detrimental to the music
