On 2010’s splashy Bom Tempo, Sergio Mendes stirs up a refreshing, tropical whirlwind. Mixing breezy bossa nova with festive horns and pop froth, “Maracatu Atomico” comforts with the warm growl of singer Seu Jorge. Mendes subtly tacks toward hip-hop on the bouncy opener, “Emorio”, which samples Tropicália classics over buoyant, larger-than-life choruses. The smooth funk of “Caxanga”, meanwhile, boasts the bandleader’s snazzy, jazzy keyboarding prowess as the bright tenor of Milton Nascimento radiates with the sunny vibes of Brazilian shores.
