Dream Theater - Mike Portnoy & Jordan Rudess Duet from the Live at Budokan DVD.
So while, sure, it’s great to come together and collaborate on songs and albums when your band is lacking what’s necessary to really pull off a score, why not simply get a group of people together that are entirely capable of playing the music you want to be creating?
There’s really no example better than Dream Theater. This little improv clip seals that into their legacy. The band members bounce ideas off each other beautifully, playing into each other’s leads and turnarounds and their technical skills leave absolutely nothing beyond their scope. You’ll notice Zappa dancing around on the screen behind them and his sound seeping into what they’re doing and then some blast beats burning through the atmosphere they’ve created.
This band doesn’t need to draw other talent in to fill out their sound. In fact, sometimes the need to get rid of people, often sending the vocalist (James LaBrie) offstage while they delve into instrumental medleys or forming solo groups consisting of the the guitarist and keyboardist or a number of other combinations of the instrumentalists. Anyway, they really drive home the point: if your band isn’t capable of completing its musical projects on its own, maybe you need to be forming a better band.
