I bought 'Bridge of Sighs' and the follow up 'For Earth Below' when they came out in 1974, 1975. I saw him live 17th Feb 1975 at Birmingham Town Hall. I must admit I tuned out for nearly forty years as Robin did a lot of bits and pieces with his band and other notable musicians but didn't really capture his early 70s magic.
But in 2013 he came out with the 'Roots and Branches' album which really caught my ear. His blues playing has matured enormously and his song writing is very strong indeed. His style is truly unique now, not just a twist on Hendrix. His last four albums have been terrific, each surpassing the previous one. Highly recommended!
