Don't want to instigate a discussion on the "importance" issue (who other than critics care about "importance", anyway? ), but I would just like to note that I am somewhat surprised about the whole Kirk hype - I cannot stand his playing (and I have probably about 10 his CDs, so this is more or less an educated statement): I find it very superficial and a total show-off fake.
I love Rollins, btw.
start a thread "Why I hate Kirk," leads to interesting discussion I have learned...
oh, but visit a doctor first. If you can't tell what Kirk is about, you may have problems with your ears...
