Q: what key would 'taste he sun' or 'it's the cambrian explosion' be in?
A: i'm terrified to listen to old material, 'taste the sun', if i remember correctly, comes after an instrumental vamp/bed (kind of like a commercial) which is clearly rooted in F#. and taste the sun doesn't really do anything crazy enough to escape that. and 'cambrian' i would say is Ab, and it borrows from Abmin (B) at the end
