Drummers: go over all of your endings and structures in general. For the songs that there are two of you on, make sure you communicate about how you're going to do the fills and when you're going to do the fills.
Singers: you should have all of your lyrics memorized by next rehearsal.
Keys: review structures, listen to the songs more often so you know when to play.
Guitarists: start thinking about pedals and tone / feel. Make a list of the pedals that you need and start getting used to making the pedals sound exactly how you need them to for each song.
Overall: we are in a pretty good spot but there is still a lot of room to grow. Listen to your songs often throughout the week.
