 Opeth's growling vocals and heavy guitars (liberally intermixed with gothic metal-evocative acoustic passages and clean melodic vocals) often see them cited as progressive death metal, yet their vocalist Mikael Åkerfeldt refers to Yes and Camel as major influences in the style of their music.Similarly, bands such as Dream Theater, Planet X, Puya, Liquid Tension Experiment, The Faceless, Between the Buried and Me and Animals as Leaders have a jazz influence, with extended solo sections that often feature "trading solos".Cynic, Atheist, Opeth, Pestilence, Between the Buried and Me and Meshuggah all blended jazz fusion with death metal, but in dramatically different ways.
