Jack Irons is a drummer who has played for the Red Hot Chili Peppers and Pearl Jam, but has since left both.

Jack has recently released his own album called "Attention Dimension" with Eddie Vedder singing vocals on Pink Floyds "Shine on you Crazy Diamond".

Jack's work on Pearl Jam's "No Code" and Neil Young's "Mirrorball" (for which, uncredited, Pearl Jam acted as Neil's backing band) are amongst the finest examples of rock drumming one will ever hear. Best examples are "In My Tree" and "Throw Your Hatred Down" respectively.
