I bought in July. I didn't like the band's previous albums, but this one is great. Prog-rock, punk-rock classical and many other genres mixed together. And it all makes sense.
The QUAD mix (DTS HD-MA 4.0 and Dolby Digital) is very good. From the front speakers you can hear the basic music, and in the rear there are additional percussion instruments, backing vocals, synthesizers, effects, additional guitars etc. I think that all these elements can be heard better from the quad mix than from the stereo mix.
Worth buying and listening to. I really like it – musically and in terms of the mix.
