"Every Heartbeat" is a 1991 single by American Christian singer Amy Grant.  It was released as the third single from the "Heart In Motion" album, though it was the second from the album to be released to mainstream pop radio.  After the unexpected major success of Grant's previous single, "Baby Baby," which topped both the United States' "Billboard" Hot 100 and Adult Contemporary charts, there seemed the question on how to follow it up.  The chosen single was "Every Heartbeat," and although it did not hit number one, it still managed to make the #2 spot on the Hot 100 and the Adult Contemporary chart for one and six weeks respectively.  In both cases Every Heartbeat was kept from the top spot by Bryan Adams' song "(Everything I Do) I Do It for You".  Charlie Peacock wrote the song's music and chorus lyrics, with Grant and Wayne Kirkpatrick composing the remaining lyrics.  In 2004, Sixpence None The Richer covered "Every Heartbeat" on the album "Full Circle: A Celebration of Songs and Friends", which commemorated Charlie Peacock's 20-year anniversary as a solo recording artist.  Mark Lowry parodied the song with the title "Every Teacher".  In 2014, the song was included on Grant's remix compilation album titled "In Motion: The Remixes".  A digital remix EP was released on iTunes in support of the album which charted at number 13 on the "Billboard" Hot Dance Club Songs chart.  In 1992 Kids Incorporated covered "Every Heartbeat" in the Season 8 episode "Old Friends".

Olga de Amaral was born as Olga Ceballos Velez in Bogotá, Cundinamarca, Colombia to parents from the Antioquia region of Colombia.  She was raised in a traditional religious family with 5 sisters and 2 brothers.  She grew up in a traditional neighbourhood in Bogotá in a warm, safe family atmosphere, maintaining a special relationship with her loving and caring mother.  Upon graduating from high school, in the years 1951-52 she got a degree in Architectural Design at the Colegio Mayor de Cundinamarca in Bogotá.  After graduation, the future textile artist worked for a year as a director of the Architectural Drawing Faculty at the same school.  In 1954, de Amaral went to the United States to study English in New York at the Columbia University.  She then moved and studied fiber art at the Cranbrook Academy of Art in Bloomfield Hills, Michigan, USA (1954–55).  The artist cherishes that period of her education and considers it crucial for her later artistic development: "In Cranbrook, the textile workshop had eight looms placed against the windows: one of them, in the corner, would be my home for a year.  There, I lived my most intimate moments of solitude; there was born my certainty about color; its strength; I felt as if I loved color as though it were something tangible.  I also learned to speak in color.  I remember with nostalgia that experience in which souls touched hands".  At Cranbrook de Amaral met Jim Amaral and they became close friends.  In 1955, after a year in Cranbrook, she returned to Colombia and started to make decorative textiles on commission for her architect friends.  Meanwhile, Jim Amaral was in the U.S. Navy, on a base in the Philippines.  In 1956, Jim visited Colombia to see Olga, initially for a few weeks.  Shortly after, Jim Amaral and Olga Ceballos Velez married and settled in Bogotá.  They started a family (children Diego and Andrea) and a workshop of handwoven textiles.  During that period, Jack Lenor Larsen visited Colombia and the Amaral's workshop.  He expressed interest in Olga's tapestries.  Their professional and artistic relationship became crucial in projection of her work internationally in the world of contemporary tapestry.  In 1965 de Amaral founded and taught at the Textile Department at the Universidad de los Andes (University of the Andes) in Bogotá.  In 1966-1967 the Amaral family lived in New York.  There Olga de Amaral met Eileen Vanderbilt from the World Crafts Council and became its representative for Colombia.  With Jack Lenor Larsen's collaboration, Olga de Amaral displayed her tapestries in New York (solo exhibition in Jack Lenor Larsen’s New York showroom in 1967), taught at Penland School of Crafts in North Carolina and in Haystack Mountain School of Crafts in Maine.  After returning to Colombia, the Amarals travelled to Popayán and Tierradentro region with its must-see San Agustín.  Later Olga visited Peru as the WCC representative.  On a rapid visit to Ireland to participate in a WCC conference, Olga met Lucie Rie, a British ceramist who inspired her to incorporate gold into the tapestries.  At the beginning of the seventies, the Amarals moved to Barcelona and then to Paris.  They visited Greece, Italy, Holland, Belgium, Switzerland, Sweden, and England.  They made contacts with the centres of European art.  They lived for a time in Europe, then returned to Bogotá, visited different areas of Colombia, and then went back to France, amid exhibits, work, and new friendships.  Another important journey for the artist was her travel to Japan.  Nowadays Olga de Amaral lives and works in Bogotá, Colombia.
