A pianist, working mainly in free improvisation, he was a floating
semi-member of King Crimson, in the years following the original Crimso Meltdown; Fripp returned the favor by producing and co-guitaring the Septober Energy LP by Tippett's all-star big band Centipede (though Old Bob missed the photo shoot). Has worked with many Soft Machine and Brotherhood of Breath alumni. Husband of Julie.
