Over the years, emo, the style of music characterized by noisy guitars and emotional/introspective lyrics, has been through a number of phases. The roots go back to the Washington D.C. hardcore scene of the '80s and extend to today as bands such as Hawthorne Heights, Silverstein and the Used play some version of emo. Expect to hear music from different time periods at tonight's Jukedown Breakdown that takes place at 10 at Mahall's. Admission is free but limited to first come, first served.
