It's so good you'll want to buy the CD. It is one of the great masterpieces of American composition of that decade, worth hearing in the highest fidelity available. Well worth a revival. You hear this, you'll forget all about that other album.
Update: In one of the most idealistic and generous artistic acts of recent years, you can find lead sheets for some of the pieces in A Genuine Tong Funeral and for many of Carla Bley, Steve Swallow and Karen Mantler's compositions at Watt Music Headquarters, in the Library.
