Velcro is a company that produces the first commercially marketed fabric hook-and-loop fastener, invented in 1948 by the Swiss electrical engineer George de Mestral. De Mestral patented Velcro in 1955, subsequently refining and developing its practical manufacture until its commercial introduction in the late 1950s.

The word Velcro is a portmanteau of the two French words velours ("velvet"), and crochet ("hook").

Hook-and-loop fasteners consist of two components: typically, two lineal fabric strips (or, alternatively, round "dots" or squares) which are attached (e.g., sewn, adhered, etc.) to the opposing surfaces to be fastened. The first component features tiny hooks; the second features even smaller and "hairier" loops. When the two components are pressed together, the hooks catch in the loops and the two pieces fasten or bind temporarily. When separated, by pulling or peeling the two surfaces apart, the velcro strips make a distinctive "ripping" sound.

The first Velcro sample was made of cotton, which proved impractical and was replaced by Nylon and polyester. Velcro fasteners made of Teflon loops, polyester hooks, and glass backing are used in aerospace applications, e.g. on space shuttles.

They were later joined by Bolichie Suzara on Bass and Alex Fidel on Drums for their debut album, "Ubod ng Lakas na Dikoryenteng Kombo". All 3 singles made top 10 in the Philippine charts. In 2007, he released his single "98 Seconds" in Germany and China.

He released his first album under Warner Music Philippines with the band Excerpts in 1999 but started getting public recognition after the release of his independent album with Velcro in 2004 distributed by Viva Records.
