Sheryl Crow [ tickets ]'s previously announced spring warm-up dates will segue straight into her extensive world tour to support her new album, "Detours."

Since last check, the nine-time Grammy winner has added another half-dozen North American shows to the fold, including a performance at the Beale Street Music Festival in Memphis. She's scheduled to kick things off with a handful of theater dates in late April and then move into amphitheaters in May, and will also headline an April 25 show at the New Orleans Jazz & Heritage Festival. An updated itinerary is listed below.

The singer/songwriter will follow the North American outing with a two-week European jaunt, details for which can be found at her website.

Crow dropped her sixth album, "Detours," last month and snagged the No. 2 spot on The Billboard 200. The record marks the return of producer Bill Bottrell, who helmed Crow's 1993 debut, "Tuesday Night Music Club," which reached seven-times platinum status and earned three Grammy awards.

"Detours" is a highly personal set of songs inspired by experiences including Crow's very public breakup with Tour de France champion Lance Armstrong, her fight with breast cancer and her adoption of a child, as well as the war in Iraq, Hurricane Katrina and environmental issues.

"The theme that runs throughout the album, which is pretty consistent, is that throughout our lives we sometimes go off on journeys that take us off of our planned path--or it takes us far away from who we think we're going to be or want to be," Crow told LiveDaily in a recent interview. "Even as a nation, I think we've seen that happen in the last seven years, just how far away we've gotten from what we were and what this country was meant to be, so politically and even personally, the album thematically is consistent to that idea."

The record's lead single, "Love is Free," pays tribute to New Orleans and its undying optimism following Hurricane Katrina. The song is currently making waves at pop and adult radio.

Crow, who's been making the television talk-show rounds as of late, will perform on ABC-TV's "Dancing with the Stars" April 8.

Meanwhile, the singer recently told AOL music news website Spinner.com that she's planning to work with Fleetwood Mac next year. However, that apparently came as a surprise to Mac's Lindsey Buckingham, who told Billboard the group has talked about the possibility of bringing another woman on board and Crow's name has come up, but nothing has been decided.
