Moves 3 to 10

The Pulsacion set is sort of a musical orphan that has been tacked on to other compilation CDs over the years, but here it is in the logical sequence of its original issue. Those who have never heard it will find it surprisingly different from much of Piazzolla's other works. Different though it is, Pulsacion still screams Piazzolla.

This 52-disc (no, that is not a typo) comp, ABC of the Blues: The Ultimate Collection from the Delta to the Big Cities, may just indeed live up to its name. There are 98 artists represented , performing 1,040 tracks. The music begins at the beginning (though the set is not sequenced chronologically) with Charlie Patton, Son House, and Robert Johnson, and moves all the way through the vintage Chicago years of Muddy Waters and Howlin' Wolf, with stops along the way in Texas, Louisiana, Florida, Georgia, Mississippi, Tennessee, New York, and all points in between. Certainly, some of these artists are considered more rhythm & blues than purely blues artists: the inclusion of music by Johnny Otis, Wynonie Harris, Bo Diddley, and others makes that clear.

The most iconic band of the U.K. glam rock scene of the '70s, T. Rex were the creation of Marc Bolan, who started out as a cheerfully addled acolyte of psychedelia and folk-rock until he turned to swaggering rock & roll with boogie rhythm and a tricked-up fashion sense. For a couple years, T. Rex were the biggest band in England and a potent cult item in the United States. If their stardom didn't last, their influence did, and T. Rex's dirty but playful attitude and Bolan's sense of style and rock star moves would show their influence in metal, punk, new wave, and alternative rock; it's all but impossible to imagine the '80s new romantic scene existing without Bolan's influence. In 1977, Bolan was killed in a car accident, and the band disbanded.
