∆ (pronounced Alt-J) is a British indie rock quartet, formed in 2007. Their debut album 'An Awesome Wave' was released in 2012 and won the impressive accolade of the 2012 British Mercury Prize. Their name ∆ (or Alt-J) was inspired by the keyboard shortcut used on Apple OS X to insert the Greek letter Delta. Their exceptional award winning album 'An Awesome Wave' holds something new at every turn for listeners. The friction between the unusual experimentation of the album and the catchiness of the songs make the album extremely different from any other album from 2012. Alt-J really are a band that can be compared to no other, creating a new genre of their own yet to be occupied by anyone else. Alt-J are definitely worth a listen, I recommend listening to their captivating song 'Something Good'.
