What better way to enjoy a night out then to go to a concert. It could be something as simple as going to see a single performer at the local club, or going to a large venue to see someone perform. It could just serve as a change of pace and allow you to explore other types of music.
For your next anniversary party think about hiring a singer to come in and perform. They could come in and keep the mood flowing throughout by singing many different romantic songs and melodies. This person could be what makes this special day even more so and one to remember for a long time.
