The stage at North Hollywood’s Palomino Club has hosted the likes of Johnny Cash, Willie Nelson, Patsy Cline, Merle Haggard, and Linda Ronstadt. The Palomino was the West Coast’s premier country music destination for 40 years, until it closed in the 1990s. But on Tuesday, the club will reopen for a concert, thanks to a collaboration between country music trio Midland and the Valley Relics Museum in Van Nuys.
