Ben Harper's career has skyrocketed from the early days of playing the tiny Mint in Los Angeles to the world's finest concert halls, theaters and festivals including the vast and muddy fields of Glastonbury, England, where he and his band played for more than 100,000 people.

A portion of profits from the sale of Ben Harper's strings go to Living Lands and Waters: Since the organization was founded, Living Lands & Waters has grown to be the only “industrial strength” river cleanup organization like it in the world. Spending up to 9 months a year living and traveling on the barge, the Living Lands & Waters' crew hosts river cleanups, watershed conservation initiatives, workshops, tree plantings and other key conservation efforts. See more at livinglandsandwaters.org.
