Ah, I like these sort of questions. As best I remember it, here is a very brief summary of what happened on each show:
Pimpin' In High Places: After the Chris Bosh Vs. Excalibur Hair vs. Hair match, the AXP ran in and attacked Excalibur, and formed an alliance with Chris Bosh. They had felt disrespected by PWG because they thought PWG had been putting the focus on East Coast talent rather than the West Coast talent. Then Super Dragon (w/brick) and Disco Machine came in and fought the AXP off. This led to this famous Excalibur promo:
http://www.youtube.com/watch?v=7CS-LjijthMTango And Cash Invitational: There were various confrontations between the two factions during these shows. Joey Ryan and Scott Lost got involved after Sky and new faction member Charles Mercury interfered in their 2nd round match with Bosh and Quicksilver.
Taste The Radness: SBS took on AXP and Bosh in a 6-man tag. Top Gun Talwar came in (as the PWG Gorilla) and turned on his fellow PWG co-owners. SBS and the X-Foundation form an uneasy alliance to combat the AXP faction.
88 Miles Per Hour: A 10-man elimination Guerrilla Games Tag Match main evented this show. During the match Scorpio Sky lays out Super Dragon with his own Psycho Driver. In a post-show promo, he challenges Super Dragon to a Guerrilla Warfare match at the next show.
Kee_ The _ee Out of Our _ool: Super Dragon and Scorpio Sky settle things in a Guerrilla Warfare match. Also on this show Bosh/Quicksilver win the PWG tag titles from the X-Foundation
The Musical: SD/Excalibur win the PWG tag titles from Bosh/Quicksilver.
That was pretty much it for the actual feud. Very soon after this the AXP faction fell apart. Bosh/Talwar/Mercury went on to a brief alliance with Disco Machine (as Sexual Tension).
