Query: Great record, but for fans of the period

There are easier places to break into Hancock's hardcore electric fusion period - and fusion in general - than this record. usually when someone refers to fusion, they're refering to a mix of jazz with some other more popular form of music: funk, rock, etc. This record is part of the Electronic Fusion/Jazz gang, and conversely will likely yield a better time for fans of ambient music or Autechre/Brian Eno/early Kraftwerk than, say, Weather Report.The album is hardcore 70s Herbie, pre-Headhunters, which is where most people come onboard with him outside of his Miles Davis gigs and "Rock It". It's not for the faint of heart, and not even the one from this period you should start with. Try "ManChild" or "Mwandishi" before you hit this one. You'll appreciate its depth more.
