operation "land0n"

More about operation "menu recovery" later. Ambitious Egghead has been given a new assignment. Yesterday, I received this sms from an unknown: "Hey text grant and tell him i cant play the drums like the faceless but i can d0 shit like that and this is land0n"
Ambitious Egghead is in no position to turn down assignments, so I text-ed "Land0n" back "ok. ill pass message. facelless?" Landon confirmed that he was on the hook, replying, "yea thanks man".
So, my assignment is this. How do I get land0n drumming to my beat? I have just begun my investigation into my new client. An e-mail address would be helpful. Who is Grant? What is the name of this band that land0n most desperately wants to attach his name too? And, most importantly, what kind of hoops must land0n jump through? As appointed band manager, Ambitious Egghead, is geared up and ready to start the virtual tour.
