I've been playing with a new band for a few months now and there's a bit of an issue brewing. The drummer in this band has names for the beat a given song will require. We do mostly jazz and a lot of the stuff we do can have a Latin beat. So the drummer will say things like 'Oh this is a Samba beat or this is a Cumbia beat or whatever and I get that these different beats can be effective to help give a song a certain feel. But... to me it should not be at the expense of the groove. This drummer has books of these different beats and he will play the beat just as it is written. Sometimes to me the feel of the song will be kind of stiff. I'm no expert at specific beats but I think I'm OK at certain Latin "feels" and I'm trying to introduce this into the music we are playing but I feel like the drummer is being kind of ridged in his approach to the music. The guys in the band are all older than me so I think they feel like they have more experience and I should just fall in with what they are doing. Whenever I mention that a song feels kind of stiff, the drummer will say something like " this is a Samba and here's a Samba beat" and he plays the beat. I haven't really ever had this issue with a band before and I haven't been able to come up with a good way to explain or demonstrate what I'm talking about. Any ideas?
