it’s funny, i have several friends with strong opinions about them and none myself
friend 1 loved the first and second album
friend 2 loved the first (mostly due to the production) but hated the second
friend 3 was in a band with producer of the first album, and when the album was really successful it helped accelerate the decline of the band they were in together. no idea if friend 3 actually likes Alt J’s music but i remember his reaction to the mention of Alt J being “hmmm yeah, kind of a shame they did so well actually…”
