i've avoided this thread because i have too many favourite vocalists, guitarists, bassists, etc. so making a "dream" would be too hard but yeah, i have nothing to do right now so i'll try...
vocals ryuichi (luna sea)
guitar sugizo (luna sea)
guitar inoran (luna sea)
bass j (luna sea)
drums shinya (luna sea)
lol! that's luna sea... ummm, ok, i'll try again... ok, it's been a few minutes of thinking and i give up! argh.
