My Penguin guide to the blues book is packed up at the moment so click the title link for a condensed version on wikipedia. Percy Sledge, Otis Redding, Jackie Wilson and Sam and Dave were my first introductions to the music that I so love now. I think I was about ten when I made my first discovery, but the very first songs to make a lasting impression on me were Jackie Wilson's "Higher and Higher" and Percy Sledge's "Cover Me". To date "Cover Me" is still my all time favorite song, if I have to choose one :)
Warm and Tender Love
Take Time to Know Her
When a Man Loves a Woman
Bring It On Home To Me
It's All Wrong But It's Alright
Percy and Rosa Sledge Live at James Ranch--got goosebumps with this one...can you imagine being married to a man that sings such love songs?
