With instrumental, you add your own story
srsly
Like, when I'm listening to the opening of Buckethead's 'Plankton' (a song), I think of fishies swimmin' around. When the riff picks up pace and gets faster, I imagine sharks closing in. Finally when the riff goes 'BOOM' and all crazy, I imagine a chase going on.
Yeah, crazy imagination I got.
But most of the time, I'm just ogling (did I sue this word right?) at how awesome the riffs and licks are.
