Marcus Mumford has said that much of the album was recorded in "non-gender specific Friday night lads sessions" with friends where they would play music, "smoke cigarettes and have a great time". Around 100 people were involved in these sessions, with some being featured on the record, including American singer-songwriters Maggie Rogers  and Gill Landry. Music and themes. "Delta" has been called an album that "draw[s] on the shared experience of being on and off" tour, and distinct from the band's "anthemic" previous album, 2015's "Wilder Mind", in that it is more "tender", "introspective and reflective". It incorporates elements of electronica, rap and jazz. It has been said to still contain the "intimacy and jubilance" that the band is known for, but keyboard player Ben Lovett said it is also concerned with "the four Ds: death, divorce, drugs and depression". Mumford spoke to Annie Mac about reusing folk instruments they  did not use on "Wilder Mind" but being "conscious [about] how we can make these instruments sound not like these instruments which opened up a whole new world for us". Critical reception. "Delta" received mixed reviews from music critics. At Metacritic, which assigns a normalised rating out of 100 to reviews from mainstream critics, the album received an average score of 59, based on 18 reviews. Commercial performance.
