After several years of touring in support of various classic albums, the reunited Sebadoh this week dropped a surprise on fans: a new five-song EP called Secret, which is both Lou Barlow & Co.’s first new music in 13 years and a teaser to a full-length album that should arrive sometime in 2013.

Lou Barlow has been treating fans to a treasure trove of free, rare and often unreleased music via his e-mail newsletter, and with his latest dispatch, he reaches back all the way back to 1983 to share a ‘lost’ 3-song practice tape from Deep Wound, his pre-Dinosaur Jr band with J Mascis.

Following its purple-tape reissue of 1988′s ‘Bug’ this past summer, Dinosaur Jr now will pair that album with cassette reissues of its first two records — 1985′s ‘Dinosaur’ and 1987′s ‘You’re Living All Over Me’ — in a limited-edition, wooden box set.

Following this summer’s cassette-only reissue of ‘Bug,’ the reunited Dinosaur Jr this fall will re-release that 1988 album along with the band’s first two records — 1985’s ‘Dinosaur’ and 1987’s ‘You’re Living All Over Me’ — on vinyl this fall, the trio’s current label, Jagjaguwar, announced this week.

This week’s new releases include 10 remastered INXS albums (without bonus material), a 2CD remastered edition of Sebadoh’s ‘Bakesale,’ Gary Numan’s ‘Replicas Live’ CD and DVD, and Joe Jackson’s ‘Live Music.’

Filmmaker Brad Katz is appealing to music fans to help fund his documentary ‘Just Gimme Indie Rock! The Story of an Underground Uprising,’ a film project he describes as ‘an epic trilogy that spans a generation’ — tracing the rise of the independent label scene in the early ’80s through the alternative explosion of the ’90s and into indie resurgence of the 2000s.
