Sonicflood (sometimes stylized as SONICFLOOd) is an American contemporary worship music band from Nashville, Tennessee. The band originally formed in 1997 under the name Zilch. The group took the name Sonicflood, a reference to a line in the Book of Revelation, chapter 19, verse 6, in 1998 as they became known as a praise and worship band following some line-up changes. They released their debut album at a time when such music was gaining commercial success in the Christian music industry. In turn, their success fed the contemporary worship music genre, expanding its appeal. Since their debut, Sonicflood has sold almost two million albums, and produced top worship hits (often as covers) including "I Could Sing of Your Love Forever", "Resonate", "Cry Holy" and "Here I am to Worship". In the early years of their existence, the group earned two Dove awards and three further nominations, and one Grammy nomination. Additionally, their eponymous debut took Gold status, and spawned several No. 1 hits on Christian radio. Sonicflood's line-up has changed significantly from its original band, partially due to disagreements over the artistic direction that they should take. These conflicts eventually left the band with no founding members. With Rick Heil at the helm since 2000, the band has continued to release albums and tour internationally.
