It's doing Live '79 a slight disservice to refer to it as simply a great live album because it is just such a wonderful album full stop. I have hundreds of albums that I love, but Hawkwind's Live '79 has long held a special place in my affections. Without question, it is my favourite ever live album, and also one of my favourite albums by anyone ever. Motorway City has transported me into a neon lit future for over two decades now, while Spirit Of The Age's lyrics make me smile every time. Then of course there is the intricacy of the melodies, and yet their accessibility.
Concluding, I would strongly recommend this album to any lover of heavy and/or progressive rock music. A legendary band at their absolute peak.
