"They'd made three albums before this that had the hits on and some other stuff that was really good, but I never really liked a whole album. There were great moments. But then Caravanserai came out and I liked the way the songs move and flow and change direction and bring in different moods and atmospheres. It was a very exotic record for me, living in Kingston in Surrey. It felt like I was hearing the real sound of the desert. The musicianship is so great. One of the things I love about Santana is that they always had great drummers. Obviously you've got Carlos on guitar, but every instrument is pushed to the front. When the Hammond player is letting rip you can really hear it. It's a very well-structured record, which back then was a very different thing to do, because it was all about the live performance, and if the song was eight minutes long you'd play for eight minutes. There wasn't the technology for any sophisticated editing so people used to play it that way to create that mood and that atmosphere. To capture that in the studio is difficult, but on this record it kind of goes beyond that. It's like somebody said there are no rules for how you do this. I don't know how to do this so I'm going to do this by instinct, I suppose. Also, for them to come in with Latin music that wasn't salsa or mariachi was unheard of. They were saying 'this is what young Mexicans do'. I just remember watching them at Woodstock and seeing [Santana drummer] Mike Shrieve and thinking my god, how do you do that? How do you play with all of them at the same time and they're all playing different things and it all works out so remarkably well?"

"I think it was Mike [Harding] from Touch who first introduced this to me. He said, 'You'll love it, and it's an unbelievable price' which is quite a killer combination if you like collecting things. I bought it and he's absolutely right. It's a master: there's no ways about it, you're hearing virtuosity, ensemble playing to the highest degree. It knows itself inside-out, which means you get this feeling of how it stretches and breathes. Basically if I'm wanting to listen to something from it I close my eyes, fumble around and take one of the six discs out so it's a surprise. Otherwise you can find something for the morning, a raga, blah blah blah. But these are just the most extraordinary devotional love songs. It's from a tradition which has been going on for a very very long time. It's not a part-time job at all; these are people who are dedicated. It's fantastic. I think it's truly inspiring in the sense that it's through listening to that that I've come upon solutions to things that I've been working on myself. It's the peculiar thing: you wake up in the morning having gone to bed with a problem or you're working on something that you don't quite know what the solution to is, and when that marvellous thing happens that all the work gets done in your sleep, it's just the very best. I had an example of that happening with this record. When Dietmar Post and Lucia Palacios were making the Transatlantic Feedback film about The Monks, in order to get the editing done they asked people if they would contribute a cover version of a Monks track. From the proceeds of that they were able to finish the editing. I was working with a Swedish friend of mine who'd introduced me to The Monks so much later than everybody else. I said he had to choose the song, and he picked 'Oh, How To Do Now'. I listened to it over and over so it got into my head and my conclusion was that we certainly can't do it like that, because the narrator of the song is obviously a young man who has extremely sexual feelings for a young lady and I thought it'd be highly inappropriate for us to pursue that angle. How do you get an in? I woke up the next morning and thought, 'I know what to do'. I rewrote their text and took the emotion down, made it more devotional and I thought, 'Ah, that's it, it's like Ali Khan'; you change it into that, so in fact it has one phrase that's basically stretched over half the song, and the other part fell into place. It's either the love or the devotion but also the sense of melody, really stretching out lines. That's an example of it being inspiring and useful."
