Alt j - An Awesome Wave Where do i begin? Alt-J (∆) is a unique band which immensely changed my view on basically everything around me. It is spiritual and their melodies are amazing. Joe Newman sings about love, crime, obsessions, fears and even sang about a french movie. The band performs acapella pieces, electronic beats and overlapping vocal pieces. They truly are wonderful. This album in particular, has their greatest tracks in my opinion. So, listen and get lost in the sound.
