[quote name='geilerbass' post='547279' date='Jul 22 2009, 08:23 AM']One of my teachers at college, Terry Gregory, also played in this style - left-handed and upside down. It really was a sight to behold and so impressive that he was able to make exactly the same sounds as someone slapping with their thumb, rather than index finger. I believe he took a lot of influence from Jimmy Haslip, having a similar approach.[/quote]
He's one of my teachers too, I've always been amazed at how he plays.
