Comalcalco is both a modern-day city located in Comalcalco Municipality about 45 miles (60 km) northwest of Villahermosa in the Mexican state of Tabasco and a Pre-Columbian Maya archaeological site. The literal English translation of "Comalcalco" is "In the house of the comals". A comal is a pan used to prepare tortillas.

The present-day city of Comalcalco reported a 2005 census population of 39,865 inhabitants, while the municipality of which it serves as municipal seat had a population of 173,773. The city is the third-largest community in the state of Tabasco, behind Villahermosa and Cárdenas. The municipality, which has an area of 723.19 km² (279.225 sq mi), includes many smaller outlying communities, the largest of which are Tecolutilla, Chichicapa, Aldama, and Miguel Hidalgo.

The site of Comalcalco, whose coordinates are 18°16′N 93°10′W, is notable for two characteristics. First, it is the westernmost known Maya settlement. Second, and due to a dearth of locally available limestone (the primary material used in architectural construction), the city's buildings were made from fired-clay bricks held together with mortar made from oyster shells. The use of bricks at Comalcalco was unique among Maya sites, and many of them are decorated with iconography and/or hieroglyphs. Important architectural features include the northern plaza and two pyramids, the Gran Acropolis and the Acropolis Este.

Isidro Chávez Espinoza (Angostura, Sinaloa, Mexico, October 29, 1981) better known as Espinoza Paz, is a Mexican musician and composer of Mexican Regional music.

Espinoza Paz was born on October 29, in La Angostura, a small colorful town just north of Sinaloa, Mexico. He was only 11 years old when he wrote his first song which was dedicated to a girl on whom he had a crush. By the time he was 13, he had already written 20 songs; however, it wasn’t until his father sent him money from the United States that he decided to buy his first guitar and teach himself to play it. In 1996, he emigrated to Sacramento, California, where his love for music grew while he earned a living washing tomatoes and picking oranges, olives and grapes. Months later, he decided to return to Mexico where he suffered the hardest experience of his life: the passing of his Mother, Mrs. Maria de la Paz Espinoza. This was a loss from which he would never recover. From that point on, Paz embarked on what seemed a never-ending journey to find his destiny. He returned to the United States (this time to Oregon) and worked as a gardener for about a year. Tired of traveling, he then decided to concentrate on his career as a songwriter, and being convinced of his calling, he returned to Mexico once again. His "muse" was a friend from California, Blanca Estrella. Their platonic relationship inspired many of his songs. For the next eight years he knocked on doors and sang in regional bands, always looking for "the opportunity" as he poured his feelings and experiences into his songs.
