"We have done 13 shows with her and every concert has been better than the previous one," he tells Finland's MTV.fi. "We are taking it day by day as much as we can. The vibe in the band is marvellous. We are enjoying every moment."
Holopainen has known Jansen, who is Dutch, for more than 10 years already, having previously toured with her former band, AFTER FOREVER.
"We are very much on the same wavelength and we have a similar sense of humor," Holopainen says of his new bandmate.
Stepping into NIGHTWISH was made easier for Jansen by the fact that she has extensive experience in both classical and rock music.
Following AFTER FOREVER's split, Jansen launched a brand new project called REVAMP, which has thus far released one album and is prearing to record a follow-up effort.
"She has been in these circles since the late '90s," says Tuomas. "She has toured a lot and has been part of this genre of music. This way, it was easier for her to enter the band."
Jansen made her live debut as the frontwoman of NIGHTWISH on October 1 at Showbox Sodo in Seattle, Washington following the
abrupt departure of the band's lead singer of the past five years, Anette Olzon.
"[Floor is] a vocal coach herself, so she's very professional," says Tuomas. "The fact that she had about 40 hours to learn 15 songs is quite
revealing. She practically learned our tour set on the flight from
Amsterdam to Seattle. We're talking about a high-level professional and
her attitude is fabulous as well. It can be seen in her stage presence. She clearly enjoys what she does."
