Honestly, not just filkers, musicians of any genre that I've met and enjoyed over the years. I just liked the alliteration!
Metricula is one of my favorite musician/singers, and we're all lucky that she is a regular on the con and event circuit. Her music runs the gamut of nerdy, funny, and serious, with an underlying country twang. I highly recommend a live show if you get the chance! You can check her out online on her site, as well as YouTube and Twitch. Twitch and Patreon subscribers get first looks at her new music, which is a great bonus! Plus, you know, supporting artists! You can also find her music on BandCamp and Spotify.
