It's interesting that I haven't heard Giant Steps played by a band in 10 years. My comment is about the article, and not about Marsalis, whom I have the highest respect for. The author should get out more, and find out whether the negative stereotype of the "self absorbed" jazz musician is actually worth perpetuating.
At least, out here in the Midwest.
Granted, I've been to gigs and jams where the next generation of young lions were blowing their asses off, on the canon of difficult Bebop tunes, but it always appeared to just a passing phase of the training process en route to becoming a mature, versatile jazz player. Likewise, my kids studied classical music, and the classical training repertoire is also over-represented on YouTube.
Today, the idea that jazz musicians are playing past the audience just has to die. It's not helping anybody, and I'm skeptical of whether it's based on actually experiencing live performances. It may be self-perpetuating in the sense that it predisposes people to experience music in a way that confirms their expectations. The bands I play with are highly conscious of connecting with the audience. This does not always mean censoring the repertoire or avoiding improvisation. We don't always succeed, but we always try.
