The Drumeo YouTube channel has a regular feature called First Time where they have drummers listen to a song they've never heard before (without drums), and create a drum part for it. They recently challenged Genesis drummer Nic Collins (son of Phil Collins) for a recent edition of this series, where Collins created a drum part for Opeth's Ghost Of Perdition. In their latest video, they brought back Collins for a new challenge with a twist - instead of having him create a new drum part, they have him try to learn a complex drum part for an existing song on the spot; the song they chose was Rush's 2112. Collins did a great job with it, and took around 2 and a half hours to learn the song. You can watch the entire process unfold below or in this video.
