Why is it there is little to no information or lessons on the relationship between the bass player and the drummer. I mean locking in with the drummer, creating grooves with the drummer, what to do and what not to do etc. I have been to most of the lesson sites and they may have a quick blurb about locking in and listen to the bass drum but that's about it and very few examples. I mean you can master all the scales, arpeggios you want but if you and the drummer are not tight then it's all crap. I still find it hard to lock in with drums because I run out of ideas pretty quick. I would love someone to provide in-depth lessons on this topic. I ordered Ed Friedlands bass groove book so I hope that helps but I am requesting all you internet bass teaches out there to spend allot more time on this very important topic.
