Bought for the Schnittke/Kremer combination, boy can that chap play!!! Let Alfred break you out of your comfort zone! The Glass is very predictable (though has some peaceful moments), has he really moved on since Glassworks? Whatever your taste (I know I'm in the minority :)), Gidon Kremer's playing will get your attention and transport you to a better place, enjoy!
Also check out Schnittke's Concerto Grosso No.1 played by Kremer, essential listening.
