Yarr and me own favorite pirate band is me own band: Sunken Chest, Portland's Loudest Pirate Rock Band.
Unlike some much other so-called pirate music, ours rocks. There may not have been rock and roll in the GAOP, but if there were, I'd think pirates would have added a booming system as part of the general terror (for others) and fun (for themselves). After all, what's more frightening, group harmony singing or the wail of guitars and the crash of the drums?
And even if it is historically inaccurate, I guess I don't care. Seems there's too much care given to accuracy in costume and not enough in attitude...but what do I know? I'm a drummer...
That's me own self-serving take, at least, and if ya likes pirates and rock and roll, then ye owes yerself a copy of the new Sunken Chest Cd! Yarr!
