There is no excuse for releasing shoddy product like this. The sonic quality is variable and mostly horrible--and mono, no less! As Craig Fenton (who should no better than to endorse this with four stars) noted, the order is all mixed up, songs fade in and out. There's distortion on most of the lead vocals. It's just a slipshod deal from beginning to end. Is the music good? Absolutely! But I guarantee you can hear much, much better Airplane from this era (though streaming only) on wolfgangsvault.com or a couple of other past '67 releases. A truly bad, unauthorized bootleg.(I am a lifelong Airplane fanatic and author of several books about the Grateful Dead...)
