Rich Martin, who's knows a bit about the fun lunacy of Hygienic Weekend, also knows a bit about the region's still-alive-and-reasonably-well rock scene.

This is why his 15th annual Rock Fix concert, taking place in his strategically located Telegraph Records Shop — where strolling Hygienic enthusiasts can come and go and come back with ease — is aesthetically tailored for maximum musical fun. Starting at 5 p.m. and running until the last power chord has sustained into nothingness, the Rock Fix boasts an eclectic and alluring line-up.

Performing are Horns of Ormus, Dr. Martino, Slept, Fatal Film, Boatweiler, Sarah Golley, and Matt Gouette. It's an all-ages show — BYOB if you've a thirst — and donations are welcome.

15th Rock Fix, 5 p.m. Saturday, Telegraph Records, 19 Golden St., New London; free, donations welcome; (860) 701-0506.
