Dirt is unclean matter, especially when in contact with a person's clothes, skin or possessions when they are said to become dirty. Common types of dirt include:

• dust — a general powder of organic or mineral matter
• — foul matter such as excrement
• — a black, ingrained dust such as soot
• soil — the mix of clay, sand and humus which lies over the bedrock

Filthy! is Papa John Creach's second solo album and the first with his band Zulu. The guitarist of Zulu would later be known as Keb' Mo'. The band Hot Tuna also makes an appearance on the album on the track "Walking the Tou Tou," written by Jorma Kaukonen.
