Having an album release party in the London Zoo's Aquarium, where the emphasis would no doubt be on stillness, hush and the haunting beauty of the deep, just suits most 4AD label releases to begin with. Given that Brook is known for his mysterious, spare guitar work makes this record of the solo concert he gave there upon the appearance of Cobalt Blue all that more appropriate. Reproducing much of the content of that album but in a different running order, Aquarium consists solely of Brook, his guitar and preset synth/rhythm patterns. The result is quite fascinating; whether a listener thinks that the more stripped-down overall sound of the songs here works better as a result or prefers the generally lusher textures of the studio release must ultimately be up to individual judgment…

The mid-'80s proved to be a prolific and exploratory time for the producer/performer team of Brian Eno and Daniel Lanois, who this time out take guitarist Michael Brook under their ambient wing to create an album of considerable beauty and restraint. Taking a "less is more" approach to the project, Brook adapts quite easily as a group member in co-creating these organic pieces (although composer credits go to him alone), and within a few minutes one forgets that he is a guitar player. Hybrid is not an especially dynamic or exciting album, but its depth is nonetheless rewarding. There is substance within the shadows, and the musicians take the necessary time to properly explore them…
