Hard Stuff was an English hard rock and early heavy metal group, which included John Du Cann and Paul Hammond formerly of Atomic Rooster. Also in the lineup were vocalist Al Shaw, and John Gustafson, formerly of Quatermass.
Du Cann and Hammond had left Atomic Rooster due to disagreements with Vincent Crane over the increasingly bluesy, soulful direction he wanted to take that band in. Consequently, compared with Atomic Rooster's more progressive leanings, Hard Stuff were based more heavily on aggressive guitar.
Originally, Du Cann, Hammond and Shaw had formed a band provisionally entitled Daemon, with the intention of eventually touring and recording under the name Atomic Rooster. Gustafson was invited to join them on that basis, but after finding out that Crane retained the rights to the Atomic Rooster name, the quartet decided to continue anyway, but under the name Bullett instead.

Bullet, the band released one single, "Hobo", the first on Deep Purple's Purple Records label. Following that release, however, they were prompted to change their name yet again, this time to Hard Stuff, due to a legal threat from a US band also called Bullet.
