premise: The Coathangers are a punk rock band from Atlanta. The band formed in 2006 as a joke. After playing a house show, they were asked to open for The Hiss on the strength of their performance. The name "Coathangers" refers to a method of self-induced abortion and was chosen for its irreverent vulgarity; all of the band's members are pro-choice. They have opened in New York City for the Black Lips.
hypothesis: Other bands have opened for the Coathangers.
reason: The context says the Coathangers were asked to open for The HIss and have opened for the Black Lips but says nothing about whether any other bands opened for the Coathangers.
