Even Song and Silence was weak on the Bard Prestige classes, at least one that a melded well with players who are not just using a bard that is a means to an end. War Chanter wasent bad but I too would like to see more bard P-classes. their's all kind of sneaky rogue like classes, but few that are good for bards. The Virtuoso (sp) ... well... I cant help but wonder what bard 'wouldent' take that class once they qualified unless you just dident like the theme.
It appears however, and some of you may have noticed this, but their have been a large number of 'bardic music' related feats latly. I'm not sure if Eberron was the catylist or if their were just many things already in the pipe line. But it seems like (and I may be wrong) that Eberron was one of the first places to have Alternate/New Bardic music abilities. Libris Mortis has a few of its own as well. All these 'few' however are becoming quite a number of choices, Almost makes me which their was a Prestige Class based around gaining 'Bardic Music based feats'.
