Unknown Progressive/Trance Tunes from Ministry of Sound (last week)

Can anybody please help me to identify any of these tunes played at Ministry of Sound last week? Apologies for the sound quality - some of them feature a lot of bass but are definitely listenable. Please, please help me identify them. Many thanks in advance :)
