a lot of blank & jones stuff sounds really similar to me, but i wouldn't say that cream or after love are similar to the rest of their stuff...
someone who produces the same track over and over under a different name is riva - all their tracks/mixes have a really similar sound to them...
svenson & gielen - twisted is a great track, but the original sounds a lot like airscape - l'esperanza in places...
but then airscape is johan gielen...
