Dan Sostrom of ToneVendor specializes in indie, jazz and experimental and while he stocks all formats, he’s bringing vinyl only to Savannah. Sostrom can track his transformation into a “music nut” to a specific moment. “The real defining moment for me was when an 8th grade classmate turned me on to Mad Professor Mike’s Coll Punk Rock Show in 1988 or so,” he said. “My musical world was turned upside down.”
