My buddy has been up to Levon's place twice for the Ramble, as they call it. He says both times were absolutely amazing "special" experiences.
Basically it's like $150 a person or something, you end up driving right into his driveway of his house in Woodstock, NY. There is a community table in one room downstairs where all the people bring food to share with others, booze, beer, etc. Bring your own, share with others, all good. You can smoke outside, bowls, whatever.
As for the music, he says there is usually an opening act, sometimes it's his daughter Amy's band, other times big acts like MMW. Levon's band is a stud lineup with guys like Jimmy Vivino or Larry Campbell playing. The music is stuff from The Band, Levon's tunes, classic rock tunes, everything. It is very intimate, about 200-225 people in folding chairs.
Highly worth the road trip (depending on where you live) and the money from what my boy says.
There are only two mantras. Yum and yuk. Mine's yum.
