4:45 AM is the third album by the Chilean prog-rock band Aisles, released in October 2013. A concept album, it is a highly melodic mixture of classic prog elements, rock riffs, fusion, and world-music flavors in a compelling, dark atmosphere. “4:45 AM is nothing short of a masterwork of art. It is the reason people fall in love with music in the first place”. Prog Rock Music Talk.
