Along with Arch Enemy, probably the best melodic death bands ever to grace the planet.
Also, they are the one of the few bands that remain constantly awesome throughtout their whole career and
don't water down their
music to attract a larger audience.
They have the most harmonious riffs ever, with nice groovy drumtracks and a spectacular keyboard
player. In fact, they are so harmonious and melodic, you swear they have an invisble conductor while they perform live.
Dark Tranquillity is also a really good
live band, as they care about their fans and the singer jumps in the crowd all the time.
However, the singer is a tad strange, as he does these really weird motions when he performs
live. That doesn't change the fact they kick ass on a biblical scale.
