The cover art of the band's debut album An Awesome Wave shows an overhead view of the largest river delta in the world, where the Ganges River meets the Bay of Bengal in Bangladesh.Īlt-J were previously known as 'Daljit Dhaliwal' and then 'Films', but were later forced to change to 'alt-J' because an American band called ' The Films' already existed. 'Alt-J' comes from the key sequence used to generate the symbol Δ on an Apple Mac computer: Alt+ J. The band often makes references to triangles (for example, the song Tesselate mentions 'triangles are my favourite shape', and they make triangle symbols with their fingers during concerts ), which they say is just due to it being a visually appealing shape. The band's actual name is the triangle-shaped symbol Δ (the capital Greek letter delta). 2.3 2013–2016: Departure of Sainsbury and This Is All Yours.2.2 2011–12: An Awesome Wave and touring.
