"ECHO Sounds"?

[Melrose]

Hey,

My father got me AT06, A Museum and A-Nation 07, but they're really strange. They're in a plastic bag of the brand "ECHO Sounds", and they are single DVDs in a transparent DVD holder (with no covers, etc. but the DVD itself has images), inside a sleeve with some images on them. What is this? It looks almost bootlegged! And the quality isn't too great either; the sound gets awfully quiet during hard parts..
