I found Wallace's Gorilla in a Cage unusually affecting in its outline and conception. This 25-minute work is dedicated to the composer's aunt, the late Edna Freedman, who fought a long bout with ovarian cancer; the title comes from an image that was once used to describe Freedman's courage and tenacity against overwhelming odds. The image is a haunting one and soloist Glennie crashed around with urgent and appropriate desperation. Moreover, Wallace has a genuine dramatic gift that keeps one watching and listening - from Glennie's catlike stalk onto the stage (accompanied by her own amplified singing) to the chiming, meditative conclusion.

Ecstasy and trance on the drums. The cheering is deservedly rapturous after this premiere performance.

Glennie rolled on her Rock-Jazz instruments including one consisting of PVC tubes called a Batonka, while the orchestra provided an ever changing, multi-coloured background. The audience was delighted with the introduction of this exotic artiste and new form of music into its habitual atmosphere.
