The five hundred and twenty-first album: #521 Blue Nile - A Walk Across the Rooftops
In trying to place this, the closest way I could describe it is as an electronic blues or soul album. It's sad and lingers on it, taking the synthesizer sound that has been used so far mostly to create upbeat, fast moving tracks, and turns it into something slow and maudlin, a rainy grey soundscape with the lyrics and vocals to match. It's not an uplifting album, but there's a lot of beauty in the careful composition of the whole album that its atmosphere has a real chance to permeate.
