I'm also a musician. I write music for my band, Tricks & Cider, and I'm available for hire to score for film and video games. I post solo videos from time to time. Here's my Facebook page, for updates on where I'm gigging next.
LinkedIn has started to be a source of sketchy spam messages, only it doesn’t catch those and file them away like Facebook does, primarily because people pay for credits (called InMail credits) to send unsolicited messages out.
