There are four projects under this name.

1. Zed was a band formed in New Zealand that later moved to America and found fame. Their first album, Silencer, was a mix of rock and a bit of techno, while their second album, This Little Empire is more pop/rock.

Soon after This Little Empire was released, the band decided to take an "extended break" as each of them have several collaborative and individual musical projects they are currently working on. Nathan King, the bands lead vocalist, is currently in the UK working on his solo career, while two other members of the band (Ben Campbell and Adrian Palmer) went on to create another band, 'Atlas'.

2. Zed is the experimental/ambient/drone monkier of Travis Nobles, currently residing in Norfolk, Virginia, USA.

3. Thrashcore punk band from Portugal. Members now in My Rules and The Youths.

4. Formed in 2005 and hailing from the Bristol area, ZED is a band that lives somewhere on the border between hard rock and punk rock n' roll, an outfit with influences and loves such as Thin Lizzy, Motley Crue, The Ramones, Judas Priest, Motorhead and Iron Maiden to name just a few.

Evolving out from the darkest, smallest practice rooms that Bristol's studios had to offer, Zed began to learn their trade starting with a collection of classic rock covers. As time went on the band continued to improve and began the long march of writing original material and developing their sound, finally evolving into a metal machine of solid drum beats, thundering bass lines, twin guitar attacks with standout solos, all this topped up with the powerful vocals and stage presence of their band leader, the formidable Colonel.
