Bubblegum XX features features members of Queens of the Stone Age, PJ Harvey, Greg Dulli, Izzy and Duff from Guns & Roses/Velvet Revolver, among other assorted rock luminaries. When Bubblegum was released, Mark chose to let it speak for itself and didn"t have much to say aside from within the small handful of interviews he did at the time. In 2017, he released a book of lyrics and writings called I Am The Wolf and wrote about the album then. Shared here are some of his words about the record. Song favorites include "When Your Number Isn"t Up," and "Strange Religion," a love song I wrote in a Tokyo hotel room. While many of the songs came from a place of dejection and ennui at the end of a tempestuous relationship, "Bombed" in particular came about when, after I had written and recorded it in just a few minutes, I put a microphone in front of Wendy Rae Fowler, my soon-to-be-ex-wife, and had her sing along while simultaneously hearing it for the first time. I loved the result as it reminded me of Royal Trux, a band I liked. When I insisted on using the first and only take of the song, it made her slightly unhappy, but to be fair, that was just one of many things I did that had that effect.
