1) Pick two somewhat popular but fairly unrelated bands.
2) Go to allmusic.com and type in the name of one of them.
3) Using only the ‘Similar Artists’ link, find your way to the second artist.
I attempted to go from the Sonics to NWA but after about 1,000 clicks only made it to Ice Cube, Dr. Dre, and MC Ren. Let us know how you did!
