Put new heads on drums, and have them tuned in advance. This is what drums sound like when they are not tuned. If they sound like this, there is a very limited number of options available to make them sound any good.

Bring extra sticks, mallets, beaters, etc.

Make sure all components are working properly (hi-hat pedals, snare levers, etc.)

Keep your range of tonal options open. Bring an extra snare. Rather than filling your bass drum with one great big duvet, maybe try a couple of smaller blankets and a couple of pillows. This allows us to try different levels of damping, rather than "all on" and "all off."

Bring Moon-gels or any other products/materials that might be useful in damping your kit.

If you have more than one kit, leave the big, live, boomy sounding kit at home and bring the drier, punchier, flatter sounding kit. A boomy kit can sound great live, but easily run out of control in the studio.

Note: If you use my kit, it will be tuned, well-maintained, etc., and I have gels, drum keys, and a choice of three snares, etc.
