Ah, flute alors. Normally, the basic drums, guitar, bass, vocals set up works perfectly fine for metal. I typically wouldn't suggest fucking with it or else you could end up with a whole string section wanking away and burying what everyone really wants to hear. And use those keyboards tastefully too. Now flutes are even more deadly. Rarely, is there ever a time where I want to hear some flute. Jean Cohen-Solal- yes. Early Jethro Tull-sure, okay. And I'm sure there's a few more. But flutes & metal, not ever. Except for this anomaly. I'm not saying it works the whole time, but it is interesting. Give it a listen.
