Let's make this birthday one to remember.

55 years old (Born on April 03, 1970)

Happy Birthday, James MacDonough! You’ve nailed down epic bass riffs with the thunderous finesse that left Megadeth fans headbanging into blissful delirium. Not everyone can effortlessly shift from Nevermore's intricate layers to shredding stages alongside Mustaine — truly a heavy metal hero’s journey worthy of legend.

Each year ticks by faster than one of your fret-burning solos, yet you remain forever timeless—like those classic bass lines we all pretend to mimic at concerts. Keep rocking the bottom end and shaking stadiums worldwide; may this birthday drop as heavy as your best setlist encore! Here's to many more years turning amps up past eleven!
