Sounds like Sugizo's playing guitar along with the drum solo, only for a few seconds.
I don't think this is a full on drum solo in the air, there's no music playing in the background either. Better to play it safe.
Ah, Yoshiki's playing his mini piano inside his drum set again, the mood he's trying to set with that is easier to understand when you can only hear it, I think.
Orchestral music is back. Yoshiki's going much easier on the playing I think.
End of drum solo.
They're doing I.V now.
