Load in cold. Go on warm.
One pack covers the gap between a freezing load-in and downbeat.
Stiff before you plug in
Gear's coming out of the van and your hands haven't caught up yet. They're already stiff, and stiff hands don't wait for soundcheck. That's where the night gets lost, before you ever plug in.
Crack it and go
Pull a pack out of your gig bag on the way to the stage and snap it open. The air does the rest. A few minutes later your hands are warm and loose.
Play the best show of your life over and over
Hands warm and fingers moving, dialed in from the first note through the encore. Warm hands own the room.
