Chicago (AFP) – One of America’s largest events — Lollapalooza music festival in Chicago — is underway this weekend, to the delight of fans and to the despair of others. The four day music festival is expected to draw more than 100,000 people to downtown Chicago each day, at a moment when coronavirus cases are on the rise and vaccinations have plateaued. Lollapalooza has said their policy is for unvaccinated people to wear masks and show a recent negative Covid test.
