They each offer something different, I think. I'm actually not that familiar with the Live album(
), though I do own it so for me it's between the polished, controlled 'show' of The Dance or the more raw and rough around the edges nature of Live in Boston. The Dance was my first visual experience of the Mac, and it was all so pretty and impressive. I'd never seen anything like Stevie Nicks before and she blew me away, and Lindsey has rarely looked better. Live in Boston as a real live show was so different to that, it took me a while to come round to it, though those versions of Go Your Own Way and Stand Back are my all-time favourites.
...I think I'll go with The Dance.
