Stick with it long enough, and there’s a good chance the mainstream will eventually come to you. That definitely applies to Yo La Tengo, a venerable alternative-rock trio that’s been making very fine records for close to 30 years. And where the group’s idiosyncratic combination of high-volume drones contrasted with pensive moodiness used to seem pretty out there a quarter-century ago, it feels positively bubblegummy nowadays. The group’s new album “Fade,” (Matador Records) consists of another 10 melodic gems, which they’ll show off Wednesday at Cat’s Cradle in Carrboro. Doors open at 8 p.m. and tickets are $22 advance, $25 day of show. See catscradle.com for details.
