The Big Gig is less than a week away, but the world's largest music festival is still adding new acts to its lineup as it announced a handful of additional headliner performers on Thursday night.

Here are the latest additions:

• Eve 6 – Saturday, Sept. 4 at 2 p.m. on the Generac Power Stage
• Natasha Bedingfield – Thursday, Sept. 16 at 8 p.m. on the Johnson Controls World Sound Stage
• Neon Trees – Saturday, Sept. 18 at 10 p.m. at the Uline Warehouse
• Flaming Lips – Saturday, Sept. 18 at 10 p.m. at the Generac Power Stage
• Gego y Nony – Saturday, Sept. 18 at 8 p.m. at the Miller Lite Oasis 
• Lunay – Saturday, Sept. 18 at 10 p.m. at the Miller Lite Oasis

The Flaming Lips show on Saturday, Sept. 18 replaces the Pixies, who were previously booked for that stage and timeslot before dropping out earlier this week due to the ongoing COVID-19 pandemic. Modern English also cancelled its Big Gig booking this week due to COVID concerns; its once-scheduled 10 p.m. slot on Friday, Sept. 3 has been filled by already-announced headliner Berlin featuring Terri Nunn, according to Summerfest's website, moving from 8 p.m. Otherwise, most of these bookings fill in previously "to be announced" spots on the Summerfest schedule.
