What kind of music do you think will be popular in 20 years? Will we even use electric guitars and basses? Will Polka make a re-surgance? Will a tuba be the best bass for metal? Maybe it will all be computer generated and performed by flawless androids that look like Tiny Tim? Will the hurdy gurdy be the new electric guitar? Will the average song last 15 seconds or the time it takes Mick Jagger to makeup his face?
