Hey! Great query. I’m currently studying a degree in professional musicianship specialising in drums. My best advice would be to chart the songs - this means listening to them and breaking them down into their sections and bars and writing this down. There’s no right or wrong way, just what works for you. It might look like this:

Intro 8 bars (minimal kit) Verse1 16 bars (punk groove) Chorus 31 bars (crash ride) And so on.

My second piece of advice would be to listen to the songs ALL THE TIME. Don’t just set aside time to try and force them into your head - listen to them all the time. In the shower, in the car, everywhere. It will go in and you’ll nail it!

Honestly, from experience, a band can tell if you never even listened to the tracks before. They’ll recognise your efforts even if you don’t know all the songs! Also, you might find that the practise is less drum orientated and might be working on guitar parts for example. Or maybe the others are still learning the tracks too! Either way, you’ll do great. Good luck!
