Former Beach Boys singer and songwriter Brian Wilson plans to record concerts at Los Angeles' Roxy Theater, April 7 and 8, for an upcoming live album. The as-yet-untitled disc will be sold exclusively through Wilson's Web site, his spokesperson said. The site (www.brianwilson.com) is slated to launch in late April or early May and will likely include a free download from the album. Among the expected cuts on the disc are previously unreleased numbers and cuts Wilson unveiled at last fall's annual Bridge School acoustic benefit concert.
