On the night of the "Enchant" release party, Autumn learned that Courtney Love had invited her to record an album, "America's Sweetheart", and embark on the tour to promote it. Contributing violin and vocals, Autumn appeared in Love's backing band The Chelsea—Radio Sloan, Dvin Kirakosian, Samantha Maloney, and Lisa Leveridge—on the 2004 tour. Much of Autumn's violin work did not get released on the album; she commented: "This had to do entirely with new producers taking over the project after our little vacation in France, and carefully discarding all of our sessions." She performed live with Love and The Chelsea on "Late Show with David Letterman" on March 17, 2004, and at Bowery Ballroom the next day. In September 2004, her father died from lung cancer, even though he had quit smoking twenty years earlier. Near the end of 2004, she was filmed for an appearance on an episode of HGTV's "Crafters Coast to Coast", showing viewers how to create faery wings and sushi-styled soap—both products she sold in her online "web design and couture fashion house", WillowTech House. On December 23, 2004, she appeared on the Chicago-based television station WGN as part of the string quartet backing up Billy Corgan and Dennis DeYoung's duet of "We Three Kings".
