Siggno (also known as Grupo Siggno) is an American Tejano band formed in Santa Rosa in 2000. The group released their debut album Al Principio in 2001 under Crown Records. The album's release followed Tejano music's post-golden age era, where artists music were indistinguishable from their counterparts, while album sales flattened. Music critics praised Siggno's progressive sounds and entertaining performances during their concerts. Their second album, Por Amor (2002) received a BMI Music Award and Latin Grammy Award nomination. The group's album Six Pack (2008) marked Siggno's first entry on a music chart. Their album Que Harias (2010) provided Siggno their first top 10 album on the US Billboard Regional Mexican Albums chart.
