In June, the House of Representatives voted to eliminate all $1.1 billion in Federal Funding for the Corporation for Public Broadcasting for the next two years. Mike Horn, who records as the cosmic ambient Seawind of Battery, is fighting back, raising money to support public radio and TV through this 19-track compilation. It’s a worthy cause, and you could justify the purchase strictly on philanthropic grounds. However, Save the Waves is also an excellent compendium of the current state of ambient, (mostly) instrumental psychedelia, topped up with contributions by Takoma-style pickers, experimental droners, slowcore dreamers and improvising guitar heroes. Don’t buy it because you should. Buy it because you want to.
