The no-name producers in Barcelona do, in fact, have names. They are John Lindland of San Francisco, and Simon Walbrook and Ben Green, both of Melbourne, Australia. Prior to The Return, their biggest claim to fame was Walbrook's having toured with Australian one-hit wonders the Avalanches, a sample-heavy electronica band.
not a surprising outcome considering kool keith is a crackhead and has been selling pretty half baked vocal loops to rubbish bands/producers for years to pay the bills (ie GT and Gerling and whoever else had some cash to buy a vocal hook)
would be more interesting if kool keith was relevant now!
