Austin, TX—The cultural season has turned here at the South By Southwest Festival, now on day seven. With the end of SXSW Interactive on Tuesday, the internet obsessives shipped out and were replaced yesterday by the cool kids of SXSW Music. Can you tell the difference between rival camps?

Five of the following people were attendees of SXSW Interactive, the portion of Southby Southwest dedicated to "emerging technologies," whom I spoke to on Tuesday. The other five are SXSW Music attendees I talked to yesterday. Take this difficult quiz to see if you can figure out who is who.
