Their 'That's The Way Of The World' album, along with the AWB's 'White' album, shaped my bass upbringing. I played those albums to death. Verdine's part on 'Shining Star' is probably one of the most innovative ever.
However, seeing some videos of EWF in concert, I'm not sure Verdine is actually playing the parts. In fact, there is so much post-production that I'm put off, and can't bear to go and watch them live these days,.
There is a DVD where they're playing a TV gig and the viewers are phoning through requests (something like EWF By Request). It's extremely overdubbed.
