So many, where to begin.....?
Sweet - Blockbuster. Though to be fair, it was the B side that opened my eyes to 'Hard Rock'. (though didnt even know it had a name at 13!)
Led Zeppelin - IV - A kid at school gave me a cassette of this he had found, blew me away.
Queen - II - After seeing them open for Mott The Hoople (my fisrt gig) and not knowing who they were, bought this and was amazed.
Cheap Trick - Heaven Tonight. Opened my ears to perfectly crafted rock with melodies.
Van Halen - Van Halen A totally new way of making an electric guitar scream..
Prince - 1999 Genius is an overused word....but he is one.
R.E.M. - Murmur Turnred me onto all that Paisley Underground stuff at the time; The Dream Syndicate, The Rain Parade, Gereen On Red, The Bangles, The Hoodoo Gurus, The Church etc...
The Stone Roses - The Stone Roses. Proved 'Indie' could have soul.
