We’re going a little off the beaten track here; Attention Please is the title track from the 2011 album of the same name by Boris, which Wikipedia describes as an “experimental band”, whatever that means. They are from Japan and play mostly extremely loud drone metal, but with occasional excursions into soft moody stuff, for example this song; they are fabulous musicians.
Most of Boris’ albums are mostly atmospheric guitar noise, but the story I read somewhere is that vocalist/guitarist Wata wanted to do some crooning and the band was OK with that.
Boris have several albums I wholeheartedly recommend; my faves are Akuma no Uta and their collaboration with Sunn O))), Altar, which has an all-star cast and also some slightly less metallic stuff.
If they’re coming near your town, run don’t walk, go see them. Wear earplugs to protect your hearing.
