Hooray for Swedish melodic death metal!! In Flames, whilst they may not have created said genre, certainly have had a giant influence on it since their inception in 1990, when i was just nine. They have managed to get through fifteen band members in their history, and the five that survived are:

Björn Gelotte - Guitars
Daniel Svensson - Drums
Peter Iwers - Bassguitar
Jesper Strömblad - Guitars
Anders Fridén - Vocals
