Tonic is an American rock band, formed in 1993 by Emerson Hart and Jeff Russo. Later members have included Dan Lavery, Kevin Shepard, and Dan Rothchild. Signed to a recording contract in 1995, the band released its debut album Lemon Parade in 1996. The single "If You Could Only See" reached No. 11 on the Billboard Airplay Hot 100, and Lemon Parade itself reached platinum status.
Tonic spent much of the next two years touring, adding to its reputation as a relentlessly gigging band. In addition to extensive touring Tonic produced other work, including songs for feature film soundtracks. After self-producing its 1999 album Sugar, Tonic released its third album Head on Straight in 2002. Tonic received two Grammy nominations from Head on Straight, including one for Best Rock Performance by a Duo or Group with Vocal for "Take Me As I Am", and one for Best Rock Album. The band then went on hiatus beginning in 2004 while its members pursued other musical endeavors. It wasn’t until late 2008 Tonic became active again, embarking on a tour and releasing a greatest-hits compilation, all of which served as a prelude to their fourth studio album, 2010’s Tonic. After the release of that album, Tonic has continued to tour and remain active into the year 2016, when they released an all-acoustic version of Lemon Parade titled Lemon Parade Revisited in celebration of that album’s 20th anniversary and which utilized direct funding from fans.
They have earned two Grammy nominations.
