I have been enchanted with B N Suresh's flute music for a long time. The tonal quality of his flute reminds me of Chembai Vaidyanatha Bhagavatar's voice. Suresh, who died of of Liver Cancer at the relatively young age of 44 in 1990, was very well known in Karnataka but was only selectively known outside (As I have written earlier, Sudha Raghunathan, the vocalist lists him as one of her favorite instrumentalists along with S Balachander and Chitti Babu). I would easily put him in the same class as Dr N Ramani.
As far as I am aware, his discography consists of just 2 albums - one which has an excellent Hemavathi ("Sri Kanthimatim" of Muthuswami Dikshitar) and a sweet "Kanjadalayatakshi" in Kamala Manohari (also by Dixitar), among others (HMV STHVS 56903). He is accompanied by Lalgudi Jayaraman, Vellore Ramabhadran, and Bangalore Venkataram. This is a must have. The other album is of Purandaradasa's kritis accompanied by Mysore Manjunath (Violin), Praveen (Mridangam), Bangalore Venkataram (Ghatam), and HP Ramachar (Kanjira). If you are aware of other albums by him, please let me know. I wish All India Radio releases his radio concerts from its archives.
Suresh's style was characterized by strong, clean, and clear tone without any hiss and an incredible control over laya (you can time him with a stopwatch - I have seen him in concerts become irritated with the mridangist or the violinist if they tended to speed up or slow down - he would put down his flute and start keeping the tala!). Like Mali, he also used a high pitched flute (5-katte) believing that it was only when the flute was played at 4 or 5 katte, that its sweetness, beauty, and clarity came through. His style (bani) was his own, having taken lessons on the flute only for a short while - he admired Mali and was influenced by him but did not try aping his style. His guru, I believe, was the Ghatam/ Mridangam player, Bangalore Venkataram who taught him by singing and having Suresh vocalize on the flute. He has also said that he was influenced by the Alathur brothers. A Suresh quirk is that he sometimes got into a manic, fast, and almost repetitive playing of swara passages with staccato notes (in the Purandaradasa kritis album he does this in the swara prasthara for the kritis in Vasantha and Shubha Pantuvarali). He does not seem to have done that in the concert posted at www.rasikapriya.net
To mark his first death anniversary, a number of rasikas and musicians from Bangalore and Mysore released a booklet called, "Poet of Flute". The book has a decent biography of him and a few articles but it soars because of the photographs it has - it has one of Suresh, as a boy of 9 in "knickers" (shorts) sharing the stage with Mali and another where he is the main artist again in knickers (age 12 or so) with M S Gopalakrishnan on the violin!
