Four full stacks and one guitar stand...
Someone likes to be heard huh.
Is that one bands gear or just a storage location? (also, looks very cold! I'm used to having the AC on full blast in our rehearsal space. It looks so strange to see you all rugged up at "training". (sub bracketed comment, I love that you call it 'training' rather than 'practice' or 'rehearsal'. Absolutely correct from a grammatical point of view I believe, but unusual in Australian English in this context.))
