Word association, Bright Eyes: Conor Oberst. Word association, Conor Oberst: poles. One of the most polarizing voices in alternative music today, Bright Eyes’ frontman Conor Oberst really knows how to run the proverbial gamut. He seemed to have seen much more than his 13 years of ages on his first precocious released recordings. He seems to still have a legitimate claim to the tag of “kid” now at age 31. Some people deride Oberst as the “Justin Bieber of indie.” Others will laud him as the ingenious voice of a generation. Whatever way you look at it, Conor Oberst is something; and usually a lot of it. That theme of polarization extended itself to the Bright Eyes’ concert last Tuesday, the 9th at the Boulder Theater. Featuring a set equally weighted between his old and new catalog, Conor Oberst put both his most mature and most child-like selves on display.
