4 tech-house / minimal tracks, played in 2010, Massimo Cassini, heard on Soundcloud

Hi!
I need to identify these 4 tracks. They were included in a set from june'2010 played by Massimo Cassini on his soundcloud page. I don't know if the tracks themselves are from 2010 or older.
Here are the links:
track-a
track-b --> Glitter - Take Over
track-c
track-d

Thanks!
