Every weekend, after I get out of work on Friday, I head back from Grand Central to the Bronx to get ready for whatever show I may be going to that weekend.
Traditionally, you buy tickets for a show and know in advance when and where you are going. With the new wave of electronic/dubstep DJ's becoming popular, the ways of going to shows have been changing.
Many times there will be a DJ playing somewhere, and the special guests won't be announced until a few hours before the show. Then people rush to Webster Hall to see whatever act was just announced. Sometimes these announcements of shows and guests are not officially announced through the venue, so social media plays a great part. If you don't know the right person, see the right tweet, or get the right text message from a secret source, you miss out on a lot of good unannounced shows! This is my greatest use of Twitter.
