Southern rock
The song uses a clever play on words to promote Southern rock music. The notion that "the South shall rise again" was a familiar sentiment and rallying cry for disaffected Southern whites after the American Civil War. The song co-opts that sentiment, but uses the statement to celebrate Southern rock acts contemporary to the song itself. The "it" that the South is going to do again, it is implied, is that the South would produce further popular Southern rock bands.
