Music and philanthropy have a long, benevolent relationship with one another. Record bins are rife with charity singles, and concert history is filled with benefit shows for every imaginable cause. Musicians like to give back.
From their '61 Cavern Club debut to their last rooftop concert eight years later, The Beatles gave every serious artist in their wake the songbook and sound for their career. It's the musical trough from which nearly every musician drinks.
Somewhere along the line, a concert became a variety show. It was no longer enough for four dudes to play together in front of some guitar amps. Costume changes, an army of dancers, and Broadway theatrics suddenly became standard for a 'concert.'
