If you already have AudioRecPro or a similar Audio Stream Recorder: Why don't you record 'Harlem Shuffle' or - better - the whole show here: [
concerts.wolfgangsvault.com].
If you don't own this devise you can buy AudioRecPro here [
www.ezaudiorecorder.com].
If you dont have the money or for other reason just are not willing to spend a buck, try to get an AudioStreamRecorder by checking torrent sites like btjunkie.org, www.saugsgtube-torrrent.to or one of the countless other sites. By the way, you can also get video-Streamers, who do the same thing for Video Streams.
If you think, that all this is much to complicated for you; Mail me, I will send you the whole show as mp3 for free. At least I'm willing to offer this for the first 10 fans who mail me. Otherwise, I would loose to much time and money.
