I saw Planet X and LTE.
The hell?
Music to sleep to:
Robert Rich, Steve Roach, Ananta, Brian Eno a.o. for ambient minimal stuff.
For more instrumental music with actual instruments, try listening to some modern classical, or classical/pop crossovers:
Les Fragments de la Nuit, Arvo Part, Steve Reich, Gerard Grisey, Johann Johannsson
Oh and a special recommendation for 'Jonsi & Alex', wich is basically Sigur Ros minus... well minus everything, just the atmosphere.
