guilhermeful dead- i would recommend mountain tracks 3 or 4. from past shows i'd recommend 10/13/05, 4/06/02, or 11/5/04. all can be found on archive
from this summer tour i would recommend 6-15-07. it was their 1000th show and the best night of my life. their 1st set kind of chronicled their playing throughout the years and the second set was pure bliss. almost an hour and a half of constant mind melting music. during the jam of 'mother's only son"(one of my favorite jams) some fireworks started going off further on down the des moines river from a iowa cubs game. perfect serendipity

6-12/14/and 16 can be found on archive. all 4 shows i saw this summer were among the best i've seen. they did an unplugged 'pan american' by hank williams to open the 2nd set at the big top. pure bliss. also, check out their nye show from this year with futureman on drums. if you like it, they're playing with john fishman at redrocks in august
if you liked their new speedway boogie, check out their demonic 'mason's children'.
