   Reaction is the second album by American R&B singer Rebbie Jackson. The album released in 1986 and spawned two mildly successful singles, "Reaction" and "You Send the Rain Away", a duet with Robin Zander. "Ticket To Love" was going to be released as the second single and received a very limited promo release before being cancelled in favour of "You Send the Rain Away". The album-only track "Tonight I'm Yours", a duet with Isaac Hayes received substantial airplay but was not commercially released as a single. Reaction received a limited CD reissue in Japan in the early 1990s. Reaction was reissued on CD with Jackson's previous album Centipede on May 18, 2010. The album was reissued by Funky Town Grooves on CD in October 2012 and included 7 bonus tracks.
