Aimee Mann and Ted Leo began collaborating, under the inconspicuous band name the Both, in 2013. Mann, a generational singer-songwriter, was, in her formative years, a punk, before coming up playing in the New Wave favorites ’Til Tuesday, and eventually turning to the wry ballads for which she is revered. Leo, a New Jersey-bred punk hero, is a biting lyricist attuned to the nuances of pop songcraft. Both are fiercely independent artists, free to follow their muses where they travel—even if that happens to be a holiday variety show that mixes jovial Christmas classics with piquant original songs.
