Not sure about having to really move around but yes, a band must put in that little something extra to make a live show work. I saw Van Morrison in Marlay Park just outside of Dublin - re-arranged venue due to the original show (closer to town) being flooded - typical July "soft" weather. Not great crowd, and a lot there were more into the more Celtic side of Van whereas the show was a full on RnB set. The band and Van were amazing, the show really buzzed despite a muted response from the crowd. Saw him 3 weeks later, same band, same set at the Bishopstock Blues Festival - audience really into it but a real "going through the motions" feel to the set. Not a note out of place but it just didn't have the same buzz as Dublin.
