I'm not familiar with that photographer (but will go look him up) but I'd think about showing concerts from setting up til after the show. Not all in one night! - or you could... then choose from those over time. This is like doing events - go early, stay late (again, not every concert) to get behind the scenes shots. And yes, I've gotten what I'd consider 'in game'event portraits but in a different place than a studio, and spontaneously rather than posed.
If it's going to be over a year's time, I'd look at what else goes on during a concert tour or between performances, what do they do traveling? or on days or nights in between performances? What goes into a performance? what is the crew doing? when/how do they interact with band members? setting up lighting? etc. etc. I'd see opportunities for photos/portraits of various aspects of the band's life.
Depends on how much access you have but over time you could probably by going early or after performances see interesting opportunities to photograph the band members besides when they're on stage. Even when you don't get a picture you may get some good stories to tell (in sports I found behind the scenes is never boring! lol).
Have fun with it! If you do it'll probably show in your photos. And of course make sure you're getting proper exposures, and framing/composing images well, etc. etc. You'll need to like it enough to hang in there over the long haul, but you'll probably come away with some great experiences and photos that tell a story.
