Hal Blaine and The Wrecking Crew were the architects of popular music during the 60's and 70's having played on thousands of thousands of tracks. No doubt his drumming influenced a generation of players and will continue to heard for years to come.
If you have a favorite musician or creator, take the time to tell them how much their art has meant to you... most can even be reached through social media. Just a simple 'thank you' is good enough while they're still around versus waiting until it's too late.
I'm glad I reached out to Hal many many years ago and was so grateful when he took the time to respond... R.I.P Hal.
