Yesterday I heard a concerto by Frederich Kalkbremmer; it was the No.2 in E minor.
It was on Classic FM and the pianist was Howard Shelley (I think).
It is the first time I had ever heard of Frederich Kalhbremmer, let alone heard the concerto but it certainly made me sit up and listen. I now want to hear his other concertos, I think there are four.
