A single world-music concert might expose listeners to the mariachi horns of Mexico, the thumb pianos of Africa, and postmodern compositions for the howling emptiness of Antarctica. Sample cosmopolitan sounds with this deal to see Ottmar Liebert at the Bing Crosby Theater. For $20, you get one ticket for upper- or lower-balcony seating on Tuesday, July 24, at 7:30 p.m. (up to a $40.25 value). Doors open at 6:30 p.m.

Ottmar Liebert leads his long-time touring ensemble, Luna Negra, through the radio singles and beat-heavy nouveau flamenco of his 25-album catalog, including his latest release, Dune. Liebert’s flamenco-guitar melodies are smooth and often melancholy in tone, suffused with elements of the upbeat rock n’ roll that was his first love, as listeners can hear in the song “Night Exhales” from his new album. When life took him from Germany to Boston to Santa Fe, he recorded a double-album, Nouveau Flamenco, whose fusion of flamenco, jazz, and bossa nova gained the attention of local radio stations and a major record label that re-released his album the following year to double-platinum sales. Five Grammy nominations later, he continues to rack up gold and platinum records every time he captures his musical escapades on record. Under the domed ceiling and golden chandeliers of the Bing Crosby Theater, Liebert’s spellbinding arpeggios act as harps at the beginning of a dream sequences, where audiences fall backward through time to the days of silent pictures and tangoing Woodrow Wilsons.
