The Musical Box, at the old Hammersmith Odeon last week. For the uninitiated, this is a French-Canadian band that recreates old (up to 1977) Genesis material. I'd seen them before, reproducing the 1973 Genesis show in its entirety and been impressed at the quality of the performance, including the singer's impersonation of Peter Gabriel (hearing a French-Canadian speaking with a slight west country accent was slightly surreal).
This was a slightly different format in that it wasn't trying to reproduce a specific tour set but instead had three "acts". There first was mainly instrumental and drew on material from the first two albums that he band made without Gabriel. The second was a chunk of The Lamb Lies Down on Broadway and the third a selection of material from 1969-73, including some less well-known songs. Some was good, some a bit patchy but overall not a bad effort.
Irrespective of what you think of the music - and I'll admit that while I was a teenage fan, some of it has not aged well - what I took away from sitting in the third row and watching the two guitarists very closely was how skilled Steve Hackett and Mike Rutherford must have been, considering that they were both in their early 20s at the band's peak. Same goes, of course, for the two musicians on stage, but they didn't also have to compose the music in the first place.
They're currently touring so if you are a fan I'd recommend popping along.
