is it hard to get the air drumming perfect for a song?  i watch your videos and when you air drum it's so perfectly synced up with the song!
yes, i have to memorize the fills and notes (like on 'i'm sad'). there are a lot of videos posted on instagram of trying to get the drum video right, fucking up, and trying again. in some cases, i actually record the drum video before the final drum part is made. that way i can think freely ("think like a drummer"), and play what feels right. then i adjust the drum track in the music according to what i did in the video. i think 'chase myself through hell' was done this way, and many others
