Dream Theater Family Tree

in

This is a project aimed at making it easy to see who inspired the bands you love or even hate. For this I try not to use any influences that the band don’t claim themselves. There will be a focus on predecessors but successors will be added as they site the band. These trees become more and more interactive as new bands are added, allowing you to click any band that has a tree and jump to it.

We want our lists to be better. If you know something that belongs on this list, let us know. When in doubt we will leave it out, so we need reliable sources.
