Lotus is a 1974 live album, recorded at the Osaka Koseinenkin Hall, Osaka, Japan in 1973. It was originally released in 1974 as a triple vinyl LP in Japan only. I used to see it in my local HMV import section, along with Mountain's Twin Peaks and could only dream of opening a copy, but it was too expensive. Eventually it found a domestic release on both sides of the Atlantic but it remains the only Santana album not to chart in USA or UK. The side long Incident at Neshabur at 17-minutes is my favourite piece on it. It is at times dense and complex jazz-fusion but it is always compelling. Thankfully you can usually pick up a 2nd hand copy for a tenner these days. A tremendous musical achievement
