I just stumbled across this guy on youtube.com; he plays guitar and harp simultaneously without a rack. He holds the harp in his mouth like a cigar and plays and SINGS that way! I'm going to try to embed a video of him doing 3 songs on German TV so you can see for yourself; he only plays harp on the 1st song. If I screw up embedding the video, you can just search Harmonica Frank Floyd on youtube.com. http://youtu.be/aga0Int7x7w
Here's one of his albums. http://www.facebook.com/media/set/?set=a.170142229688612.28370.100000785081290&type=3#!/photo.php?fbid=310697368966430&set=a.170142229688612.28370.100000785081290&type=3&theater
i "discovered" this guy a few years ago. i was and still am amazed. since i don't play guitar i would never need to do what he did but he surely found a unique way to accomplish what he needed. ---------- http://www.reverbnation.com/jawboneandjolene
