Rock N Roll Cocktail | 29 followers on LinkedIn. Jason Miller is a tech blogger and social media strategist by day, and a rock ‘n’ roll photographer by night. He inadvertently shot his first concert in March of 2011 when he found out that he had a photo pass for a Motley Crue show he was covering for his music blog. Not knowing anything about shooting concert photography, he purchased a Nikon 3000 and turned to the Internet.
