The Silver Jews don't tour. That's an accepted fact within the indie community. And yet, 15 years into a career limited to the fitful release of albums such as the new ''Tanglewood Numbers," there they were on the Middle East Downstairs stage Sunday night in front of a sold-out crowd. ''This is only our eighth show ever," announced singer-guitarist David Berman, promising a return next year.
It's hard to tell what the response will be if he makes good on that. The rarity of the visit allowed the Silver Jews to get away with what might have otherwise been considered a lazy performance. There was a ramshackle charm to their music, as three guitars washed into one another in a blurry reflection of laid-back 1970s California country-rock. But Berman was never able to snap it into focus.
