||"Four Pieces of ROCK" was written in 2017 by Dennis Lester. "Four Pieces of ROCK" is a solo for a four piece Drumset with one or two crash cymbals. Grooves lead to fills that are musical and useful for young players. A Metric Modulation transforms the Rock Groove to a Shuffle Groove and comes back the same way, to the original Groove. Have fun with it and “Rock ON”, Y’all. Also available as a PDF.
