Meet my friend Djordje:
I first met him in his native Belgrade Serbia. I'll let his website tell you more about him, but let me simply add that beyond being a fine fellow, he also happens to be the best "slap" style upright bassist I've ever encountered, either in person or on record. He's got skills and techniques that simply boggle my mind. Did I mention he was a nice guy? He even gave me a hat.
Check him out.
