May I suggest the following:
Artist; Mary Fahl - On the Run
Album: From the dark side of the moon
Specially going fron track2 to track3: On The Run
At the beginning of the track her voice swirls round in circle overhead - you are literally forced to look up to see if you have speakers in the ceiling!
Tracy Chapman - Give me one Reason
Front soundstage is amazing and one can clearly visualise each instrument's placement.
Artist: CAN - SPOON Album Ege Bamyasi
Great dynamics
