A couple fantastic clips of the great Eddie Gladden today, with Horace Silver in Umbria circa. 1976 and with Dexter Gordon at the North Sea Jazz Festival circa. 1979.
Gladden isn't a drummer that's often mentioned (I learned about him via Ralph Peterson Jr. who sang his praises) but one can sure appreciate the level of intensity he played with from the excerpts compiled below (more complete footage of both these two concerts can be found on the YouTube!)
