This superb compilation of Richie Ray and Bobby Cruz focuses of their work of the late '60s and early '70s. Ray's sterling piano technique complements to perfection Cruz's formidable vocal skills, as the their two-trumpet lineup soars to unknown heights. The compilation boasts good sound, which keeps their timely ideas fresh and delightful. "Agúzate" sounds as energetic as ever and "Sonido Bestial" features a memorable Richie Ray solo (with the help of Chopin's "Revolutionary Etude No. 12"). Some material from their Fonseca years is available ("Yényere" and "Comején"), as well as "El Diferente" from the UA Latino catalog. For those who are unfamiliar with the talents of this great outfit, this is a perfect way to get started. A must-have for '60s and early-'70s salsa fans.
