So-Lo is a Danny Elfman album recorded with Oingo Boingo. The band chose to record the album as a backup band for their longtime frontman to circumvent a dispute with their label. There are two versions of the album; the second version replaces the original version of "Gratitude" with the version from the Beverly Hills Cop soundtrack.
Recorded at Ground Zero Control in Santa Monica
John Avila is not credited with performing on the album, but he does appear in the "Gratitude" music video. He was a member of the group by the next album.
