Amplifier is a bi-weekly podcast, not a full-length documentary. If it were the latter, we could easily dedicate a few hours to the work of Jim Brock, the Charlotte music veteran who has been heralded by various publications as one of the best drummers alive. Between performing at the White House for President Bill Clinton and logging six decades of music (with hundreds of percussion instruments) with Grammy Award winners like Janis Ian, Kathy Mattea and The Eagles’ Joe Walsh, Brock has made North Carolina his home and has found space for his Native American heritage.
