Having been a dedicated Fleetwood Mac fan (until they abandoned the blues for pop) I was well aware of Peter Green's reputation and playing. When he dropped out of sight after leaving Mac, many of us wondered when and if he'd reappear. He did - with this all instrumental album. At the time this came out, I was only used to hearing Green play in the context of a song or short jams like "Searching for Madge"/"Fighting for Madge" on "Then Play On," so this album didn't grab me. Even in 1970 at the age of 17 I was getting tired of long 'guitar jam' music, since there was an overabundance of it and most of it frankly sucked.BUT!............Once I got past the fact that there was no singing and really started listening to this album, it became aparent that Green wasn't simply noodling. The improvs build and climax and subside nicely. There are, to be honest, places where the mood sags a bit, but this is easily overlooked and balanced out by the (many)places where Green's playing catches fire. When he's on - which is often here - he's really on. What Clapton took ten notes to say, Green could say with one or two, which often led to him being overlooked by those addicted to the flashier playing of Clapton, Hendrix, Page, Beck, etc. But make no mistake, this is a ROCK SOLID album and well worth the price.
