I can't remember when I first heard Tor Lundvall's work, but I've now got 3 of his albums I tend to play back-to-back. Out of the 3, Empty City is my favourite.
It's the kind of ambient music that mixes big spaces with intimate voices to create a definite mood. And it's equally great played in any season. It changes slightly if listening in Winter or Summer, but fits both.
Some of his later albums have a mix of instrumental and lyrical tracks.
