Tori Amos: a female singer/songwriter who happens to play piano. Only a vague similarity, really. Neither are 'rubbish', to say so just shows ignorance. Both are, though, 'Marmite' singers, and I wouldn't have it any other way. Imagine if all female singers were copies of Sheryl Cole...
Tori used to release large numbers of covers as extra tracks on her singles, (until the record industry decided that it was 'too hard' on musicians to produce extra music and reduced the number of tracks for eligable singles to two).
I've got covers of Zeppelin, Nirvana, Joni Mitchell, Billy Holliday, Chas and Dave...
And Tori is a briliant live performer, when she performs 'Me And A Gun', about being raped by a fan, she's mesmerising.
