I recently post about guitar player telling the drummer what to do it ended up breaking band among other reasons . If drummers did not Play there own soul on the kit music would sound pretty much like a drum machine ? We dont get drumming icons and New music styles . I watched a Petty interveiw from his early years and on . His drummer was responsible in part for the Petty sound and Tom was pissed when he found out his drummer was leaving Petty him self stated that the band was use to his style and sound and to replace that was a drag .
