Besides the whole "concept album" thing going on here, the most influential part of the album goes back to that same first track. "3030" is one of the only hip-hop songs I've ever heard that has real dynamic to it. The song changes and progresses as different samples and layers are added and taken away. This track manages to not get boring, not even for a second, throughout its 8 minute entirety.
I also just read the fantastic news that all three original members, Dan the Automator, Del, and Kid Koala, are making a sequel to Deltron 3030, entitled "Deltron 3030: Event II".
Download the album for free here, then anticipate the new one like crazy.
Other awesome albums by Del or Dan the Automator include Both Sides of the Brain, and the first Gorillaz album... although pretty much anything these guys do is amazing. (See Handsome Boy Modeling School, Hieroglyphics, Kool Keith's Doctor Octagonecologyst, etc...)
