Beach House released B-sides and Rarities in 2017, which served as a proverbial "cleaning out the closet" to pave way for a new creative process. Their approach in the creation of 7 was rebirth and rejuvenation. Victoria Legrand‎ and ‎Alex Scally used to limit themselves to what they thought they could perform live, but this time that limitation was ignored. Also, instead of one long studio session, Beach House recorded when inspired batches of songs, which resulted in 5 mini-sessions over the course of 11 months. Unlike the last four albums, 7 didn't have a producer in the traditional sense. Spacemen 3's Sonic Boom (Peter Kember) became a significant force on this record by shedding conventions and helping to keep the songs alive, fresh, and protected from the destructive elements of recording studio overproduction and over-perfection. The band's trusted live drummer from 2016 to the present, James Barone, played on the entire record, helping to keep rhythm at the center of a lot of these songs.

"Looking back, there is quite a bit of chaos happening in these songs, and a pervasive dark field that we had little control over. The discussions surrounding women's issues were a constant source of inspiration and questioning. The energy, lyrics and moods of much of this record grew from ruminations on the roles, pressures and conditions that our society places on women, past and present. The twisted double edge of glamour, with its perils and perfect moments, was an endless source (see "L'Inconnue," "Drunk in LA," "Woo," "Girl Of The Year," "Last Ride"). In a more general sense, we are interested by the human mind's (and nature's) tendency to create forces equal and opposite to those present. Thematically, this record often deals with the beauty that arises in dealing with darkness; the empathy and love that grows from collective trauma; the place one reaches when they accept rather than deny (see "Dark Spring," "Pay No Mind," "Lemon Glow," "Dive," "Black Car," "Lose Your Smile")." - Beach House
