From the band website, http://www.twilight-guardians.com:
"This is to let you all know that after 29.8. 2008 Twilight Guardians exists no more as a band. It´s also the date of our final show in our hometown of Salo. There are absolutely no personal conflicts involved and we remain the best friends hopefully the rest of our days.....So what happened?
We just lost the enthusiasm and sincere joy for our thing. We have been playing as Twilight Guardians for over 10 years now and lately it hasn´t been that fun anymore.
