About Evans Drumheads

This American brand has been doing heads since 1956 and it is possibly the most innovations it has made in recent years in the manufacture of heads. Their constant advances have much to do with how we hear the batteries today both in recordings and in directs.
Today an important part of drummers and percussionists from around the world and all styles have Evans as a travel companion in their careers.
Putting the list of artists using Evans would be endless but we could set Jojo Mayer, Dennis Chambers, Pat Mastelotto, Joy Jordison or Billy Cobham as an example
