The Local Natives return with a collection of smooth-sounding melodies on their second album, “Hummingbird.” Unlike their excellent 2009 debut album, “Gorilla Manor,” these 11 songs reflect a notable sadness, with gloomy lyrics suggesting a deeper level of thought about life and death.

The band spends the album trying to tackle bigger issues, leaving their listeners to analyze abstract topics like the relationship between soul and body. The track “Heavy Feet” accompanies its darkened beat with lines about immortality, questioning issues that connect the emotional with the metaphysical.

“Colombia” reveals feelings focused on more personal emotions. Written by band member Kelcey Ayer as a dedication to his deceased mother, the lyrics are heart wrenching: “A hummingbird crashed right in front of me, and I understood all you did for us,” sings Ayer. The slow pace of the song also accents the dimensions of his pain.

Although the tone is much different from “Gorilla Manor,” the band continues with their impressive harmonies, with powerful vocals from members Taylor Rice, Ryan Hahn and Ayer. The instrumental aspect of the songs is also likable, such as the tambourine complimenting the guitar and drums in “Breakers.” The melody for most tracks is relaxed with the occasional fast tempo.

From the light-hearted “Gorilla Manor” to “Hummingbird,” Local Natives can be defined as a maturing band, developing their own flare into a sound that can stand on its own. Listeners should anticipate their appearance on stage during the Coachella Valley Music and Arts Festival this coming April.
