LONDON: One of Britain's most prestigious orchestras has performed to a rather unusual audience – row upon row of plants, in an attempt to see whether the music helps them grow. The Royal Philharmonic Orchestra performed a three-hour recital in Cadogan Hall in London last week, with 33 musicians playing pieces including Mozart's Symphony Number 40, it announced Thursday. In front of them were more than 100 different varieties of plants and bulbs including geraniums, fuschias and perennials.
