No, the blues is not that.

1) Most of the titles in this compilation of 4 cd (I do not know vol.1) are not played by the creators, so these are times, usually small quality. 2) There are very few true blues here, but the English blues-rock of the 60s and early 70. 3) Some titles, so few, are original (Gallagher ...), they naturally float. So all the P. Green, but one or F. Mac are times, poor occasions. 4) The sound is unsatisfactory: too much treble, and guitars and harmonicas are poorly mixed. 5) While you can listen distractedly. But it is frankly not great, there is so much better compilation of blues and blues rock, not to mention of course the original indispensable, which are very easily, almost, findable. "Eagle records" has accustomed us better. But, hey, you can listen.
