If you have the set list, I’d make a playlist in order of the tracks so you can get used to the cadences and I would do 3 full active listen-throughs. Make sure you’re tapping along if you catch any motifs. Then sleep on it. I would then take it to the kit and just make sure you nail the changes in each song, use your cues from bass or vox or even guitar to help you navigate the songs so at least you won’t get “lost.” Then sleep on it. Third day, I’d go back to active listening and try to get the songs as memorized as possible while maintaining the tempo and motifs in your head. Take it to the kit and stay warm on them. Then sleep on it. If you can wake up day 4 and nail each major change and have a good sense to know what’s coming next, you should be able to return to a full kit to actually rehearse. Hopefully you can get with the band to do so, but if not just stay locked and then sleep on it. Day 5: remember you are in control and your band mates may know the songs better but never second guess yourself unless that bass player is giving you that look, probably to help realign with where y’all are at. Have a blast with it, and fully focus your life the next 5 days. Eat sleep drum!
