Live Karaoke with HariKaraoke

Guests can show off their best rock 'n' roll moves with the HariKaraoke Band, a live, four-piece band that backs amateur singers. Performing in the Washington area since May 2010, HariKaraoke can play for corporate groups for up to five hours, offering a catalog of over 300 songs that guests can sing along to on stage via an iPad displaying lyrics. And if a performance is truly painful, guests can bang on a gong a la The Gong Show— all in good fun, of course. Pricing starts at $1,350 for two hours with the band for Friday and Saturday events within 50 miles of D.C., and from $1,050 for two-hour events Sunday through Thursday.
