Fania records founder Jerry Masucci nurtured a group of musicians who collectively defined the New York-based Latin American dance music called salsa. Masucci packaged his stars in touring revues patterned after the R&B revues mounted by Motown, Stax/Volt and others. The Fania All Stars could thus play such large venues as Yankee Stadium and Madison Square Garden, promoting both their individual careers and recordings such as Rhythm Machine, which features some big-name jazz guests. Ruben Blades leads a stellar vocal lineup that includes Adalberto Santiago, Hector Casanova, Ada Chabrell, Nancy O'Neill, and Johnny Pacheco, who also plays flute and percussion. Jon Faddis and Randy Brecker are the headliners of a four-piece trumpet section, backed by three trombones, flutes, harp, vibes, and other assorted instruments.
