Silver Jews, a Nashvillebased outfit started by the prolific Stephen Malkmus before his other, better-known band, Pavement, was cemented, may be the most famous group you’ve never heard of. And they seem to like it that way. Their frontman, David Berman, was the subject of a documentary this past year, but otherwise, they’ve long stayed on the DL, turning out pensive rock albums loaded with Berman’s lyrics, which would likely tickle Dylan Thomas’s fancy. Their sixth album, Lookout Mountain, Lookout Sea, hit shelves in June, and this summer’s tour is only their second time on the road. Call it stage fright or call it a marketing ploy — we’re not sure, but we’re glad they’re back. The Middle East Downstairs (472 Mass Ave, Cambridge, 617.864.3278) is their Boston-area stop. Also on the bill is Who Shot Hollywood and local crooners Hallelujah the Hills. Tickets are $15 and available at www.ticketmaster.com or at the Middle East box office.
