I see someone's signature line with the Southwind 2017shown above/below. I have also seen a blurb on the DCA side with Cadets 2 doing their show based on "Appalachian Spring" with "Appalachian Morning" by Paul Winter added into the show. If these are correct, I have updated my Rhapsody/Napster playlist for all who would like to hear the source music. You can find it under Drum Corps 2017 and it includes both DCI and DCA source music that has been identified as of today.
And no, I didn't fall for the SCV April First announcement. However, I have to give them credit on a well developed prank.
