Marc Ribot 'Spiritual Unity' in Italy

Kind of a weird question or two for you... I have just found that Marc Ribot is doing this thing in Italy in August, coincidentally within the week or so that I am planning to be in Italy! The one drawback is the show seems to be on the island of Sardinia... so, a question for the Italians: if I am 'sightseeing' in Rome, is it a major detour to get to Sardinia? Or is it a simple matter of getting on a boat for a few hours? Just want to know whether this excursion is feasible... Oh, and anyone who has seen Spiritual Unity, how is it? I'd be happy just to see the guy in the flesh just playing his guitar at all, but it would be nice to know what to expect... is it a very intellectual thing, or good fun, or a bit of both? Thanks, Julian.
