PDXjams.com was a website active between 2009 & 2013 dedicated to promoting jam bands based in Portland, OR, in a format similar to jambase.com. We posted over 1,000 shows here, along with profile pages for bands -- over 50! -- and venues.
Everything was in a database, allowing for automatic crosslinking via PHP -- listing by band, venue, or date -- and a custom CMS made it efficient to input shows. The website was created and maintained solely by Jeffree White.
We still use the companion Facebook page for occasional announcements. Please post your shows or band there and we'll echo it. Note that we promote bands based in Portland only.
Poke around; the shows page now displays all 1000+ shows (and the band and venue profile pages list all past shows applicable to them), and the bands and venues lists still have useful links in there -- and some bands are still active!
There are no shows on the pdxjams calendar at this time...somebody's slacking!
band list cleanup; new "inactive band" list
