"haunting, mesmeric, hypnotic"
"Ambient and minimal; hypnotic and attractive; mysterious and tonally deceptive; beautiful and even refreshing."
I don't know that I'm with Eric on "refreshing" though, particularly regarding their first piece/set. I think I'm more with the guy who wanted to laugh in response to the sensory overload; at the time I think I described it as "the soundtrack from a nightmare" or somesuch, so if I had laughed it would have been more of a hyperventilated crazed cackle. I much preferred the second piece; it evoked a summer storm with rain on a tin roof for me.
"Ambient is not something I’d choose every night, but The Necks were engrossing and satisfying and much recommended."
Definitely engrossing, but I could only recommend The Necks to folk who're open to the unorthodox, or ambient soundscape performance veterans.
