No, this is not a physcis thing.
However, you may think you used to live in a tiny universe after you have spent an hour or two in the grip of these musicians. Small venues and up close are best.
I really enjoyed their performance at Bumbershoot last year and wish this relatively short set was amongst the over over 100 shows available for download or streaming at the Internet Archive.
If you like the music burn some copies for yourself and your friends, attend a show next time they are in your area and, yes, buy a CD or two.
And, while you are at it, thumb your nose at the RIAA and its albatross clients.
