'Roxy & Elsewhere' is possibly my favourite album of his and I pretty much know every note and every word. It's totally surreal to finally see it all with my own eyes. Also interesting to fully notice how much Zappa eventually changed live albums by cutting, splicing and overdubbing.
The video and sound quality are amazing and I love how there are no annoying special effects and the camera isn't all jerky, showing long, clear shots of the musicians. A must-see for everyone who likes Zappa.
