Hi Joe,

Just heard your podcast for "Redshift Riders" It sounds very cool. I was a little puzzled by your explanation for "using redshift" What you described sounded more like the gravitational slingshot that they use to accelerate spacecraft. Redshift refers to a lengthening of measured wavelengths due to objects moving away from each other as well as the expansion of the universe-sort of like the lowering of pitch as an ambulance siren speeds away from you.

Just in case you're interesting. Looking forward to the album and seeing you in concert again.
