The band of brothers will kick off their next round of live performances with a couple of shows at Austin's South by Southwest festival in mid-March. "The Walk Tour" will officially roll out April 9, starting with four shows across Wisconsin and then traveling around the eastern half of the US through May 7. Indie rockers Stephen Kellogg and the Sixers, and singer/songwriter Kate Voegele will support the trek. Dates are listed below.

Fan club members will have access to pre-sale tickets at Hanson's website beginning tomorrow (2/26), and the general on-sale starts Friday (2/29).

Last year, Hanson supported its fourth studio set, "The Walk," with a tour that included a one-mile, barefoot walk in each market to help bring attention to poverty and AIDS in Africa. The band also teamed with TOMS Shoes, which, for every pair of shoes sold, donated a pair to a needy child.

In November, the brothers announced they reached their goal of selling 50,000 pairs of TOMS Shoes.

"The idea of partnering with TOMS and taking one mile walks barefoot in every city on the Walk Tour started as a crazy idea that we never thought we could really pull off," Isaac, Taylor and Zac Hanson said in a joint statement. "Now we have walked 28 miles bare foot, with thousands of you who have joined us. For everyone who has walked and purchased a pair of TOMS, the song 'Great Divide,' or the Great Divide T-Shirt, you should feel proud to know you have taken one step to fight poverty, and stop the cycle of AIDS/HIV."

Charity single "Great Divide," which Hanson recorded in Africa and released in November 2006, benefits African AIDS relief organization HIVSA.

The song appears on "The Walk," which Hanson released on its own 3CG label last July. The set was inspired in part by the brothers' trip to South Africa and Mozambique, where they recruited children from a local orphanage to form a choir. "Great Divide" and a few other tunes from the record are streaming at Hanson's MySpace page.
