Delain is the band from Martijn Westerholt. This guy is famous for his work with Within Temptation, though he had to leave this band because he was ill.
When he felt better Westerholt started to make some music again, called some famous friends and recorded the album Lucidity. After the recording sessions he searched for band members, he created a band and the rest is history.

I don’t understand the release from this single. The single contains two songs, a video clip and a sticker.

The songs ‘Frozen’ and ‘(Deep) Frozen’ are also on the full-length and the video can be found at sites like youtube and myspace. So I think this release is just for the fans (you want a free sticker from Delain? Mail me at news@rockezine.com and I’ll sent it to you) and to give the band some more media attention.
So I’ll give them some attention. The band is on the road throughout the Netherlands, so check them out somewhere near you!
