I saw that Genesis had remastered a 5.1 version of the Lamb when I made the link to the Genesis website. You found the bass and ambience improved, huh? I'll have to check that out.

Do you have a copy of Genesis - Live, the live album from '73? It has Musical Box and The Knife on side one and Watcher of the Skies, Get 'Em Out by Friday and Return of the Giant Hogweed on side two. I don't know how they managed on what must have been a pretty lean budget back then, but it is excellent quality, especially for a live performance. They were able to capture that elusive crowd ambience and give make it sound 3D. They also cought what's just as hard, to mic every instrument and make them sound balanced, without leaving something out or over emphasizing something else. Vocals are pure, no distortion and cymbals are crisp.

The record carries the Charisma label and was distributed by Phonogram. It was recorded at the De Montfort Hall and the Free Trade Hall in Laicester and Manchester, England, respectively. The album was mixed at Island Studios in London, and produced by John Burns and the band. The net effect of all these efforts is a really great album, so check it out if you don't have it already. It was easy to overlook, because the sleeve design and photos made it lok like a pirated knock-off or something. But it's great.
