In 2007, Miyuki started planning her new concert, called "Concert Tour 2007", which was a very special concert. So, when she wrote these songs, it was to stand in concert and customize them with the feeling of thinking about how they should be performed on stage. The concert was a great success and is probably the most popular after the "Calendar" concert. That's not to mention the fact that Miyuki recorded a live video of the concert and released a DVD and Blu-Ray version of the video. This is a truly precious gift for Miyuki listeners who didn't get a chance to be there. (It's an unprecedented event, because Miyuki had always thought of the concert as a kind of bonding between her music and the audience, a "one-and-done" event, so she seldom left images for release. (Actually, 2006's 34th album "ララバイSINGER" was Miyuki's preparation for this concert)
