Who Killed The JAMs? is the second studio album by The Justified Ancients of Mu Mu, and the final one under the JAMs moniker before renaming themselves The KLF. Similar in style to the preceding 1987 , the album is a fusion of hip hop, drum machines and samples of a diversity of musical works, although in general the samples are more covertly integrated here than they are in 1987.

James Francis Cauty, also known as Rockman Rock, is an English artist and musician, best known as one-half of the duo the KLF, co-founder of the Orb and as the man who burnt £1 million.
