Their early material was hard edged blues-rock influenced by Bo Diddley and Jimmy Reed, much like that of their contemporaries like the Stones and The Yardbirds. They were known for wild "rock and roll" behavior and shocking the establishment; their song "Midnight to Six Man" defined the Mod lifestyle. Beginning in 1966 they drifted more towards psychedelia, with the 1968 concept album S.F. Sorrow. From this point on they would enjoy less in the way of commercial success but the devotion of a strong cult following, especially with critics and other rock musicians as well. Their material in the early 1970s tended towards more the hard rock and early heavy metal end of the spectrum, on albums like Silk Torpedo, although still blues based. 1980's Cross Talk saw them incorporating influences of punk and new wave into their hard rock sound; like most of their records, it was an artistic but not a commercial success.
PrettyThings was preceeded by Little Boy Blue and the Blue Boys which consisted of Dick Taylor, fellow Sidcup Art College student Keith Richards and Mick Jagger.
Their early material was hard-edged blues-rock influenced by Bo Diddley (they took their name from Diddley's 1955 song "PrettyThing" in humerous contrast to their unkempt long-haired appearance) and Jimmy Reed, much like that of their contemporaries The Stones and The Yardbirds.
The PrettyThings were among the many band and artists that employed session drummer Bobby Graham, who played on their first two albums.
