“I want all of Los Angeles to hear this!” Adam Levine exclaimed Friday night at the Greek Theatre, where his band, Maroon 5, played the first of two hometown shows over the weekend. Levine was urging the audience to sing along — and loudly — to “This Love,” one of Maroon 5's earliest hits, but his request served also as an indicator of the L.A. group's demographic ambition: At a moment when many musicians view stylistic specialization as a way to reach listeners overloaded with options, here's an act deeply devoted to the big-tent approach.

Levine and his bandmates used their 90-minute set Friday to showcase the various facets of Maroon 5's sound. In “Wake Up Call” and “Stutter” — the latter from the group's third studio album, “Hands All Over,” released last month — they were hard-rock road warriors, bashing out muscular riffs over stomping beats. “If I Never See Your Face Again” and “Give a Little More” were lighter and funkier, with guitarist James Valentine channeling Nile Rodgers of Chic; a glittering disco ball descended during “Give a Little More,” emphasizing the music's hot-stuff heritage.

The Gibson will have several Latin music acts, including Gilberto Santa Rosa, Pepe Aguilar and Vicente Fernández. Sugarland, the Go-Go's and Norah Jones will play the Greek.

System of a Down's Serj Tankian, Spanish tenor Jose Carreras, L.A. rockers 30 Seconds to Mars, kid-friendly group the Wiggles and the MTV Movie Awards are among the highlights of the 2010 subscription concert series being announced jointly Friday by the Greek Theatre and Gibson Amphitheatre.

Offerings include many veterans making return visits to the two facilities as well as a number of newer acts injecting some freshness to the lineups.

Tankian will bring his ambitious "Elect the Dead" symphony, from his 2007 solo album, to the Greek on July 30 with accompaniment from a full orchestra. Carreras also will appear with symphonic backing June 26 when he plays the Greek for the first time in 15 years.

The Gibson's schedule again features a plethora of Latin music acts, this year including the L.A. Salsa Festival with Gilberto Santa Rosa, Luis Enrique, Willy Chirino and Oscar D'Leon (May 7), Conjunto Primavera (June 12), Pepe Aguilar (July 16-17), Alejandro Sanz (July 23-24), Marco Antonio Solis (Sept. 25) and the venue's annual fall series of appearances by Vicente Fernández (Nov. 12-14).
