Right now, Weezer are in the midst of yet another goofy-ass project in a career full of them. This year, the band intends to release four EPs, each one of them tied to one of the year’s seasons. They dropped SZNZ: Spring in March, and they followed it last year with SZNZ: Summer. (They also announced a forthcoming Broadway residency.) Weezer have also roped poor Jimmy Kimmel into this scheme. In March, the day after they released the first EP, the band, along with a mandolinist in a bunny costume, did musical-guest duties on Jimmy Kimmel Live. Last night, with the new EP out in the world, the band returned to Kimmel.
