The first time I listened to Monty I cringed at the blaring C64 noise notes. It progressed from acceptable game track at 0:40, to neat faux guitar rock song at around 3:00, then the crazy finish at around 5:00 – nope, the real flourish starts at 5:30. I even liked the descent back to the more primitive sounds at the end.
The other chiptunes in the dome were fine, but Monty is the only one that’s been added to my work rotation.
