Although they ended up sounding too smooth and glitzy, EWF started up as a fantastic Jazz/Funk fusionband. They found their own sound around ´73/´74 and if you really want a taste of how good they were live, listen to Gratitude or ´Alive in ´75´. Fantastic groove and melodies, vocal harmonies and horn playing. Things started going south when guitarist Johnny Graham left over money disputes. After Faces/Raise, they were more or less a carbon copy disco band to my taste, especially after keybordist Larry Graham left and they changed their horn section. For a great read, try and get Philp Bailey´s book ´Shining Stars´.
