Most readers will question the validity of introducing the works of such a little-known composer to the shelf, but this CD shows that even historical underdogs deserve their moment in the sun. The Philadelphia Virtuosi bring vibrancy and energy to Antheil's vivid soundscapes, which are amoung the most progressive works of the 1920's. To put Antheil's contributions into relief, the Ballet Mechanique on the present recording was first performed in 1926, predating the other famous avant-garde work for percussion ensemble of the era, Edgard Varese's Ionasation, of 1931-33. Of additional note on the record is the exemplary solo playing of the participants in Antheil's quirky quintet, the Symphony for Five Instruments of 1923. However, for those interested in the profound pinnacles of early 20th Century music, this disc may fall short of such inflated expectations. The music on this disc is primarily intended to divert and to delight. Influences of the Stravinsky's L'Histoire du Soldat and of the early works of the so-called "Les Six" group conjure a reasonable example of what Antheil's witty scores have to offer. The program notes by Joshua Cheek unfortunately leave much to the imagination of the listener. For instance, the respective ensembles of the Symphony and the Concert are not enumerated, leaving the listener guessing as to the timbres he is hearing. Otherwise, congratulations to the Philadelphia Virtuosi and to Naxos for an interesting, welcome program with fine playing, polished sound and an alluring price tag.
