Categorized labels and artists on one page. It's under construction
(since long), and much of it has been transferred to PsyDB, but

Psychedelic Mind Expander
Largest specialized psytrance / chillout artist and label database
online. This is the one and only reason we don't include artist/label
websites in this portal. Online since 1995.
The one and only music bible. Not too many psytrance releases
and biographies, but the functionality and large collection of
various biographies and reviews are both an interesting read and
a great resource.
The largest specialized open source electronic music database.
They're expanding nearly as quickly as records are released.
