Alt-J ∆

∆ (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'.

Jake Bugg

Jake Bugg is an incredibly talented 18 year old singe songwriter from Nottingham, United Kingdom. His soulful voice is older than his years and has similarities to Johnny Cash and Bob Dylan to the extent in which he has been given the title of an 'East Midlands Bob Dylan'. After the release of his début album 'Jake Bugg' which achieved number one in the UK album charts, Bugg's popularity is steadily increasing. His music is well worth listening to and the striking diversity of his voice in prominent in all his songs. You would never believe that such a mature voice comes from someone so young. I recommend listening to 'Two Fingers' and 'Country Song'

Imagine Dragons

After failing to publish any new posts for a staggering five months, I felt I needed to return with a bang, hence why I am recommending the incredible Imagine Dragons. Imagine Dragons are an incredibly talented and underrated American alternative rock band based in Las Vegas. For those of you experiencing winter blues cheer yourselves up with what will no doubt be the song of summer '12 'On Top Of The World'. This song has already attracted attention due to featuring on the Fifa 13 soundtrack, which has turned into a rather prestigious accolade, this song is well worth a listen and perfectly depicts the wonderful sound of Imagine Dragons.
