Music From Scratch using the C64 BASIC Prompt

Live coding and algoraves have become a popular music making method in recent years, but here we have lftkryo showing how it's possible on C64! In the video he shows that there are no built-in commands for generating sound, with what he describes as some absurdly technical coding - shouting out Walt of Bonzai for his help and inspiration. Here's more:
