Why "Circus" is a tip? Because many do not know how well (yes, great!), This album of Lenny, if you take the time to delve into the rich treasures of these songs. Like no other work of this artist is "Circus" characterized by complexity, energy, strength, depth. Lenny Kravitz makes easy what made him so successful: his music. Which is perhaps more difficult to access on this album, but all the better. He plays again with tones and sounds, with moods and imagination. An impressive body of work, in which he allows an insight into his soul, in which it opens and leaves gush its versatility. From party songs to goose bumps and more, rock and pop, loud and quiet, but always good, always Lenny, always at the limit of what is possible.
