Chithra, singer.

Many of you, like myself, might have heard songs sung by Chithra. She is not famous like many of her contemporaries. I am not sure whether she sings in other languages !!???. But her voice is very attractive and absorbing. This is the first female singer's voice which impressed me!!. Though lata mangenskar, S Janaki. Ratnamala praksh, arun(to name a few) are very good but I was never impressed.
Which voice impressed you most?.
