Dinosaur Jr frontman J Mascis returned to “Late Night With Seth Meyers” last night to promote his latest album, Tied to a Star, performing the single “Every Morning” on air, and then sticking around for a web-only cover of Mazzy Star’s 1993 hit “Fade Into You.”

B-52s co-founder Kate Pierson will make her solo debut next year with the release of Guitars and Microphones, a 10-track album described as “marrying party rock, psychedelia and socio-political punk” and featuring songs co-written by Sia and a guest appearance by guitarist Nick Valensi of The Strokes.

]t’s been a busy few days in New York City for Bob Mould: On Wednesday night, he played Bowery Ballroom, inviting “Portlandia” star Fred Armisen on stage to play guitar on three rarely played ‘Flip Your Wig’-era Hüsker Dü songs. And then on Thursday night, he appeared on “Late Night With Jimmy Fallon.”

Dinosaur Jr guitar savant J Mascis is no stranger to deliciously awkward interviews, so putting him head-to-head with “Portlandia” star Fred Armisen’s near-lookalike character Candace — co-proprietor of the Women and Women First feminist bookstore — was an inspired bit of promotion by Jagjaguwar Records.
