hello- long time no visit. i'm a drummer preparing to jam with a bassist who has decent theoretical knowledge and a pretty good ear, but no experience playing with any musician. i want to do more of a free-form jam session, where we each play something and work off one another, but this bassist prefers to play cover tunes. i find this a little counter-intuitive to my idea of jamming, which is 'take what you know and try to work off one another'. i figured we'd do standard rock, blues, jazz, funk progressions, trade fours, that kinda thing. the notion of playing covers while there's no other musicians to round out the rest of the songs seems odd. to me, covers are something you practice on your own time. what do you think is a good expectation/approach in a drums/bass jam session? and regarding covers, do you think my point is valid, or it's important to play covers as well, in this instance? peace & thanks.
