Derrick Mc Leod has 3 Tonic concerts.

Vocalist/guitarist Emerson Hart formed the alternative/roots band Tonic in 1993 with guitarist Jeff Russo (a childhood friend), bassist Dan Rothchild, and drummer Kevin Shepard. After gigging around Los Angeles, the foursome signed with A&M Records. For the recording of their debut album, producer Jack Joseph Puig (Jellyfish, the Black Crowes) gave Tonic a decidedly rootsy feel, with the addition of lap steel and mandolin. The album, titled Lemon Parade, was released in July 1996.
