Over the next few years, lineup changes were common and frequent, and although retaining a basis of Latin rock, Carlos Santana's increasing involvement with guru Sri Chinmoy took the band further into more esoteric music, which continued for many years, although never quite losing the initial Latin influence.
Santana first came to public attention after their performance at the Woodstock Festival in 1969, when their Latin rock provided a contrast to other acts on the bill. This initial exposure made their first, eponymous album a hit at the time, followed in the next two years by successful follow-ups Abraxas and Santana III. They have received ten awards for the Grammy Awards and three Latin Grammy Awards. They also received four Guinness World Records. Their album Abraxas were inducted in the Grammy Hall of Fame 1999. Santana has been awarded for a Grammy Award for six songs, all of each getting one award, except "Smooth", which was awarded with three awards. Their album Supernatural received 2 awards in 2000. They received most of their awards in 2000, with eight, bating "Blues for Salvador" (received in 1988) and "The Game of Love" (received in 2002). Santana has also been awarded four times by the Guinness Book of World Records.
"Smooth" is a collaboration between Santana and Rob Thomas of the rock group Matchbox Twenty. The song was written by Rob Thomas and Itaal Shur and sung by Thomas. Originally conceived by Shur as a song called "Room 17", the lyrics were stripped off and the track was given to Thomas. Thomas re-wrote the lyrics and melody and re-titled it "Smooth". Thomas acknowledged that his choice of lyrics was "mostly ironic". Thomas' original thought was to have George Michael sing the song. Thomas recorded the song as a demo to play for Santana. After hearing the song being sung by Thomas, Santana decided to have Thomas record the final version. Matt Serletic produced the record and it was released from Carlos Santana's album Supernatural and became a massive hit in 1999, entering the Top 40 of the Billboard Hot 100 on August 10, 1999, and spending twelve weeks at number one on the Billboard Hot 100 beginning October 12, 1999.
