We like to see creativity with advertising, and NiN (+Devo +A Perfect Circle +alot more)'s Josh Freese has done just that with his new solo album.
The album itself can be bought for $7 as download, $15 for CD, $50 with a phone call from Josh, $500 for the album and joining him in a sensory deprivation tank, $20,000 for golf with Devo & 2 songs about you and $75,000 for him to join your band for a month, take shrooms with him, and cruise in Danny from Tool's Lamborghini... as well as the CD.
It all shows the unique methods artists can use to get their music promoted online, bypassing traditional methods and getting talked about. For more, including the full list, see http://mashable.com/2009/02/20/josh-freese-album-promotion/
