Yes Barun Kumar Pal is quite amazing! Was he playing guitar or was he playing the lap slide guitar thingy? That's what I've seen him play on youtube. Quite amazing. I think you turned me onto him a while back.
Also a good point that, with these guys, as with jazz and other forms of classical music, speed is just another tool. Fast is slow, slow is fast, legato is staccato, it's just, whatever you wish to do. Which is unlike rock music where we have put so much emphasis on fast playing and what have you.
