Beginning with Jones and continuing with Wood, the Rolling Stones have developed what Richards refers to as the "ancient art of weaving" responsible for part of their sound – the interplay between two guitarists on stage. Unlike most bands, the Stones follow Richards' lead rather than the drummer's (Watts). Likewise, Watts is primarily a jazz player who was able to bring that genre's influences to the style of the band's drumming. The following of Richards' lead has led to conflicts between Jagger and Richards and they have been known to annoy one another, but they have both agreed it makes a better record; Watts in particular has praised Jagger's production skills. In the studio, the band have tended to use a fluid personnel for recordings and not use the same players for each song. Guest pianists were commonplace on recordings; several songs on "Beggars Banquet" are driven by Nicky Hopkins' piano playing. On "Exile on Main St.", Richards plays bass on three tracks while Taylor plays on four.
