I am not sure whether you can play an instrument while casting spells (does anyone have a reference for this), but you clearly cannot cast spells while using any bardic music effect. So there is not much use in this fact (unless hiding the spellcasting in the musical performance).FrankTrollman posted:
3.5 nerfed Perform, so you'll have to choose whether you play an instrument (which can be done while casting spells), or sing (which can be done while fighting).
Also, I do not see any statement in the SRD which prevents a bard from playing an instrument and fighting at once, although this is quite hard to imagine for most instruments and weapons used by a two-handed character.
