That means AC/DC, Led Zeppelin etc etc, so while there are some obvious inclusions here there are some notable absentees. There is also the issue that the collection opens with a BASS riff - I know, I know it's a bass "guitar" - but hopefuly you will know what I mean. There are also some other "dubious" bass heavy entries such as "higher ground" by Red Hot Chilli Peppers and "peaches" by the Stranglers along with those riff-fests "wonderful Land" by the Shadows and "make me smile" by Cockney Rebel, decent enough songs, but "greatest" guitar riffs? No.
So what we have here is yet another "Rock" compilation that to be fair manages to juxtapose EMF with Iron Maiden and the Beach Boys with the Ruts which may be a first, but check the track listing and if you are any sort of a "rock" fan you will already have 90% of these tracks already so while a decent enough collection this is hardly a Must Buy.
