Complex is the second studio album by Australian art pop singer-songwriter Montaigne. It was released on 30 August 2019. 　　Prior to release, Montaigne said the tracks on the album "all came together over a couple of years and each song pertains to a different period of my life." She said "It's basically a series of portraits of all of my insecurities, or the weird relationships I've been in, or neurotic feelings I've felt while being attracted to others. The album's like this veil behind which I stashed all these secrets I was keeping from myself." 　　The album was supported by a 13-date national tour in November 2019.
