Like many I've had the CD of this as a favourite for years but the DVD includes all the (at times) amusing "visual/audio interludes" between the songs and the DTS mix on a decent 5.1 system is WAY better than the CD, not far off being there, well, "ish". Seriously, they have done a great job of the transfer, it sounds wonderful!
If you like Nirvana and have never heard the CD then you MUST buy this, it is one of the most stripped down, talented, raw live performances I've ever heard. Simple, musical, inspiring.
