I wasn't able to access either the article page (it's blocked behind a Cloudflare/JavaScript check) or web search/fetch tools (permissions weren't granted), so I don't have any actual article content to summarise. Based only on the title, I can tell you the piece is about Hayley Williams (Paramore) bringing out guest performers — including Karly Hartzman (Wednesday), Jenny Lewis, This Is Lorelei, and Lucy Dacus — during a set at the Newport Folk Festival, but I can't responsibly produce a two-paragraph factual summary or TLDR without details like when this happened, what songs were played, or further context, since I'd be guessing.

If you can grant WebSearch/WebFetch permissions, or paste the article text directly, I can put together the full summary right away.
