Discussing the album's legacy, Brown revealed that the recognition "did not initially happen in America. At home we were a bit under the radar. Most people at the label didn't really understand how we fitted, or didn't fit, into what was happening in music at the time." The band played the album in full in the UK in September and October with support from Mike Doughty and The Hipstones.
