The second time I heard Alt-J my sister was already hooked on Breezeblocks, listening to it on repeat, not missing a word.
The first time was when someone posted Breezeblocks on Facebook.
Since that second time I have found myself smitten. Their songs are slightly hypnotic and have interesting lyrics. When I close my eyes and listen to the album an Awesome Wave I can imagine myself floating in space or swimming in a turquoise ocean.
Have a listen and tell me what you think:
Or listen to the whole album here:
