Since issuing its full-length debut, Forge & Flagon, 10 years ago, the UK punk band Skinny Lister has been plenty busy. After Forge & Flagon’s release, it toured with Flogging Molly and played big festivals such as Coachella. Despite its track record as a festival act, the group still visits small halls like the Grog Shop in Cleveland Heights, where it performs tonight at 8.
