Fresh off the Metallica residency in Las Vegas, and 3 shows into their U.S. solo tour, Greta Van Fleet has had to postpone all shows between tonight and April 2nd because of pneumonia contracted by guitarist Jake Kiszka serious enough to have him hospitalized for four days....apparently, Jake and his brother, singer Josh, got sick at the same time, but Jake's case is way worse, so he's recuperating at home, and the band hopes to make up all the postponed dates, then hit the stage opening for Metallica in Chile on April 27th...Here's more on all that, including the band's personal message to fans: https://ultimateclassicrock.com/greta-van-fleet-postpone-tour/
