Progressive rock

There are several bands with that name: 1. Minneapolis outfit Salamander began as a duo in the summer of 1992 featuring Erik Wivinus and Sean Connaughty on guitars and vocals. They played mostly mellow drone-based instrumentals that in retrospect sounded much like contemporaries Labradford or Low. Doug Morman joined on bass in early 1993. They recorded and played gigs as a drummer-less trio until Bryce Kastning joined on drums and keyboards in early 1994.

There are multiple artists with this name: Apollo was formed in 1969. They released one album, Apollo (1970). Their music was occasionally heavy and the band sounds like Led Zeppelin or Procol Harum, with little bit King Crimson in it. Members have been in other Finnish progressive projects.
2) Apollo Indie Dance / Post Punk band from Ballarat, Australia. They Began mid 2009 when two kids decided to constructively channel their boredom in the form of melodic sound.

There are four bands with this name:
1. Punk band based in Melbourne, Australia
2. Northwest grown band based out of Salem, Oregon.
3. Norwegian prog rock.
4. Boston-based electronic, rock band.

dredg is a progressive alternative band from Los Gatos, California, USA formed in 1993. Their first studio album, Leitmotif, was released by the Universal music label on September 11, 2001. Prior to that, it had been self-released by the members of the band. After the album hit music stores, Dredg acquired an almost immediate cult following thanks to Leitmotif's unique sound and concept. There has also been a movie planned for release as a music video for the entire album, though the project has been scrapped due to the death of the lead actor.
