Apparently it isn't "officially" available yet since the release date is listed as September 7, the same day as their show at Club Congress, but the new Chicha Dust album, Live at the Dust Ballroom, is on Bandcamp now for your digital enjoyment.
“¡Live At The Dust Ballroom!” was recorded on June 9th, 2013 at the Wildcat Storage Facilities in Tucson, AZ. In the true fashion of our band we decided that throwing a party with our friends and family was the only way to capture the energy and passion that live in these songs. We brought a recording and video setup into an empty warehouse and threw a Tucson cumbia party. All of these songs are covers from the Roots of Chicha compilation and are the songs that we built this band on. We hope you dig em! ¡Viva Tucson! ¡Viva Cumbia! ¡Viva Chicha!
Listen to the album, via Bandcamp's preview player, below the cut.
