Jayan reads Devidayal’s The Music room, and recommends it strongly:
Though this is biographical in nature, and not having most of the fictional qualities, Namita Devidayal uses the method of writing, which is a combination of both styles, retaining the admiration of the art and the gurus as you often observe in biographies, as well as the use of language as in fiction writings. At no point of time she is away form the events and the stories, always retains her ( and the readers) interest in the stories and anecdotes. A very well written book and great value to someone like me who has near zero knowledge of the Hindustani Music and its heroes.
