(Debuted October 15, 1988, Peaked #53, 13 Weeks on the Chart)
In 1988, "Peek-a-Boo" sounded a lot different from what was being persented as hit music at the time. It was both refreshing and unsettling. And not surprisingly, it wasn't a pop hit because there was little room on the Hot 100 for nonconformity in 1988.
However, the song caught the ear of college radio, where the nonconformists tend to be more easily located. That burgeoning audience was finally served with its own survey when Billboard debuted its Modern Rock Tracks list on September 13, 1988. The very first #1 song on that chart was Siouxsie & the Banshee's "Peek-a-Boo."
Studio effects were used to give the song its distinctive sound. First, a recording that was recorded but not used on an earlier album was flipped upside down, with an accordion, bass and extra drum beat added. Siousie Sioux also recorded different lines of the song on different microphones, giving a sonic "image" of coming from different directions when listened to on headphones. The entire production took a year to finish; what was originally intended to be a B-side for another single eventually became too good to bury on a record.
