"When in Rome" is a live DVD by the legendary British rock band Genesis, capturing their performance at Circus Maximus in Rome, Italy, on July 14, 2007, during their highly acclaimed "Turn It On Again Tour." This tour marked the reunion of the band's classic lineup of Phil Collins, Tony Banks, and Mike Rutherford. The decision to make the Rome concert free was a heartfelt gesture of gratitude from Genesis to their Italian fans, who had been loyal supporters since the band's early days in the 1970s. This extraordinary event drew an estimated audience of over 500,000 people, not only from Italy but from all over Europe, making it one of the largest concerts in terms of audience size ever recorded.
