First of all, Amazing Baby are about to tour with Phoenix, which will probably incite a bunch of unnamed FADER editors to scream like teenage girls at the front of the audience at the New York show next week. But prior to that, the band came through Heathers for an Open Bar session which includes a gentle rendition of "Headdress," fake mustaches, some mid-afternoon beers and an acoustic bass. You really know a band has made it when they have an acoustic bass. Seriously. When was the last time you saw one of those?
