After seeing my brother's jazz teacher solo unrelentlessly through several varying pieces I was left wondering - Which is truly greater, a bass solo that is better that in sounds (e.g. Jeff Berlin ) or a bass solo that sounds better than it's content (e.g. Gary Willis' un-paralleled lyrical solos)? You dont have to be genius to discern the brain power and wealth of study pouring onto Jeff Berlins bass during his solos. Neither do you have to be a genius to tell that the Gary Willis' solos are largely governed by his ears (and pentatonics). Gary Willis' approach seems to consist of squashing his crazy harmony down to an "easy to deal with" level, exactly the opposite of what Jeff seems to be doing. So I put the question to you - is it better to compress the musical content and float through solos on a few great sounding notes or to expand the musical content, and make something new, diverse and complex? I realize this is opinioned based so please discuss!
