I'm not 100% if the band is over, but if they are, The Gathering.
Their last concert (that I could see) was in 2014 and featured, I'm pretty sure, every former band member joining them for different songs. Sounds like an amazing way to go out. Just wish they released a DVD and not just audio.
I hope The Gathering aren't done, as their last record was really good.
I guess with Kaddisfly, the same can be said per they made their last record after being gone for 8 years, and it was really both for the fans and to complete the trilogy of albums they did. But like many fans, I am very much hoping they find the means to make more music in the near future.
