Part 3. Exercise
One truly great song (the first on the disc) followed by 11 weird takes on Mexican folk music and depressing moans. The brilliant arrangement and accompaniment of the first song "Mi Cara de Pared," a sexy, mournfully loping tango, led me to expect greatness within, but alas, Lhasa is a one-trick pony, one with a potentially great voice, which is reduced to strained yodelling on the subsequent uninteresting numbers. It's almost as if she were undecided what category she wanted to present herself in - is it world music? Latin? Pop? Rock? Unfortunately it seems to be none of the above. If I want Mexican folk songs, I'll call Linda Ronstadt. The arranger and producer (name forgotten) should have waited to present the CD when he had more tricks up his sleeve and the singer had better songs. A great disappointment - but that first number is a killer.
Answer:
Negative
