I found this video while scanning for guitar techniques last night. This is a video of the winner at the World Record Speed 2008 by Brazilian guitarist Tiago Della Vega. He performs a supersonic version of “Flight of the Bumble Bee.” I have never heard of this guy is but he has incredible dexterity. Notice that the video displays the current beats per minute he has to maintain. If you watch to the end he accomplishes and incredible 320 bpm.
