One of the treasured LPs in my collection from the mid-70's is "Lotus" by Santana. "Lotus" was a special project by Sony Japan, who wheeled in an entire recording console to one of the concerts in Japan by what was then known as the New Santana Band. This band had recorded "Caravanserai" in 1972, which marked a new more jazz-focussed direction by Santana, and the same band would record "Welcome" in 1973. This was the tour to promote "Welcome".
Sony Japan, being the perfectionists that they were, recorded the whole concert, mixed it and released nearly all of it on 4 LPs as "Lotus", complete with extensive packaging and sleevenotes, with some beautiful artwork. For a long time "Lotus" was only available in Japan. Apparently CBS declined to release it outside of Japan unless it was edited down to a double LP, which Santana reportedly refused to agree to.
I bought my vinyl copy of "Lotus" secondhand in Manchester in 1975 for what was a tidy price at the time. This is a unique LP in that you get to hear a great band playing superbly in excellent sound quality, and you get to hear virtually the entire concert in the same sequence as they played it in the auditorium. (It is a little-known reality that tune sequences in live albums are often significantly different to the actual concert).
One of the most impressive features of "Lotus" is the great bass playing by Doug Rauch, who had joined the band in early 1972 to replace original bass player David Brown. Rauch was in his early 20's and this was his first major band role, but he sounds like he had been in the band for years. Listening to this concert, his playing is perfect for the band soundscape - tight, sinewy yet melodic. He sounds as bedded into the band as Berry Oakley did in the Allman Brothers at the time.
Sadly, Doug Rauch fell victim to the music industry drug culture. This short Wikipedia article explains how his career stalled out due to drug issues, and he died in 1979 of a drug overdose before he had even reached 30. However, it also explains how he was the pioneer of the double-thumb approach to hitting the strings, a technique since popularized by Marcus Miller and Victor Wooten (among other players). He was in some respects ahead of his time, and "Lotus" shows that he was an excellent all-round player, especially considering his age at the time. Sadly he did not live long enough to make his mark in music.
