by far the coolest thing i've ever seen on stage is when a local acoustic virtuoso (yes... he's an acoustic virtuoso) named michael kelsey broke a G string on stage (he planned it...) then pulled one out of his pocket and played the violin on his guitar while playing legato.... he kept singing the whole time... then he strung the string up... while playing the other 5 strings legato.... then tuned the string while he started to play all 6 strings together... then he did a little bit where he looped a riff and stretched the string.... while he sang "hold on just a little moment... i got to... i got to... stretch my string...." and he broke down in a one hand drum solo on his guitar while he plucked and stretched his string with the other hand... then tuned it up and broke into the rest of the song.... i've never seen anything like it. check out www.michaelkelsey.com. the guy is nuts. he won guitarmageddon in 2004 with an acoustic guitar...
