Sundaysounds is the project of Steffen Petry (last.fm username ygrer) from Germany. His music was assigned with a lot of different music styles and described as "melancholic post-rock" by himself. Steffen Petry - the only member of Sundayounds - learned about the post-rock genre in late 2006. He started to experiment with different sounds and techniques which resultet in the song Yearning (Isabella 2) which he - at this time under the name Steffen Petry - published on last.fm. Within 2006 and 2007 more songs were produced and put together as the album Sundaysounds.
