is the second studio album by Santana
, the Latin rock n' roll group led by guitarist Carlos Santana
. Consolidating their live success at the Woodstock Festival
in 1969, and the interest generated by their first album
the band took some time to issue a follow-up. Released in September 1970, the album's mix of rock
and other influences made it a classic that defined Santana's early sound, and showed a musical maturation from their first album.
Often considered Santana's greatest album, it drew widespread acclaim for its mixture of Latin influences with familiar rock themes such as overdriven electric guitar, organ and heavy drums. The album also demonstrates Santana's stylistic versatility, including tracks such as "Samba Pa Ti" (a classic slow-burning, seductive piece) and "Incident at Neshabur", both being instrumentals. The latter has several rhythm and time signature changes consistent with its jazz feel. Latin percussion — congas, bongos and timbales, as well as a conventional rock drum setup, make this Santana's first foray into true Latin rhythm. In 2003, the album was ranked number 205 on Rolling Stone magazine's list of the 500 greatest albums of all time.
