Henry Buckley Jr. aka Sadiki previously known as Pancho Kryztal (born 17 November 1971, Kingston, Jamaica), is a Jamaican-American singer, songwriter and producer.

Unfazed by the lack of commercial success on his first major release, he returned to Jamaica in 1998 and recorded "Rescue Me" on the Bookshelf riddim with dancehall producer Tony "CD" Kelly (Sean Paul, Lady Saw, Mr. Vegas, Super Cat).

In 1999, at the suggestion of reggae producer "Computer" Paul Henton (Shabba Ranks, Beres Hammond, Shaggy, Jimmy Cliff), he was changed his name to Sadiki – an Egyptian name meaning "faithful or loyal" (misspelled Sadeki on some earlier releases).

Sadiki again returned to Jamaica in 2001 where he scored a major dancehall hit with "Gal Dem Everytime" on the Buyout riddim for reggae producer Tony "CD" Kelly.

Morning's Come also featured production from top reggae veteran producer Lloyd Campbell of Joe Fraser Records (Glen Washington, Freddie McGregor, Marcia Griffiths, Tarrus Riley), England's top reggae producer Chris Peckings (Bitty McLean, Gappy Ranks), Delly Ranx (Sean Paul, Mavado) and Arif Cooper (Guardian Angel riddim).

The first album – Lifeline is a collaborative effort teaming Sadiki with veteran producer Lloyd Campbell and Jason Sterling of Joe Fraser Records.

Through his travels Sadiki has shared the stage with Buju Banton, Gyptian, Shaggy, Wayne Wonder, Maxi Priest, Marcia Griffiths, K-Ci & JoJo, Beenie Man, Gerald Levert, Kelly Price among others.
