Fresh off its Extended Midget tour in support of its self-titled third Interscope/DGC album, Weezer has begun recording a slew of new songs for its next set, tentatively due for a spring release. Demo versions of 13 new songs -- including "Porcupine," "Dope Nose," "Sandwiches Time," and "December" -- are available in MP3 form on Weezer's official Web site. Earlier reports acknowledged that the band has written more than 30 new songs since the release of the latest album.

The group has set aside March for touring Europe, with stints in Portugal, Spain, and the U.K. in the works. Three of the Spanish dates (March 13, 15-16) will be package shows put on by telephone company Moviestar, featuring headliners the Cranberries, Dover, and a local band in addition to Weezer. In May, the group will hit Japan for an 11-date stretch.

In other news, Weezer recently shot a video for "Photograph," the third single from "Weezer." The clip is in the mastering stage of production, and a "Web release" of the finished product is in the works. The track peaked at No. 17 on Billboard's Modern Rock Tracks chart early last month.

"Weezer," which debuted at No. 4 on The Billboard 200 last June, is currently at No. 154 in its 32nd week on the chart, and has been certified platinum by the Recording Industry Association of America (RIAA) for U.S. sales of over 1 million copies.
