Happy Birthday today (April 24) to drummer Shannon Larkin of Godsmack. He's 49. Other rockers celebrating include bassist Jack Blades of Night Ranger (62), bassist Joey Vera of Armored Saint and Fates Warning (53), and drummer Doug Clifford of CCR (71).

Godsmack formed out of Lawrence, Massachusetts in 1995. The bands current lineup includes singer Sully Erna, guitarist Tony Rombola, bassist Robbie Merrill, and drummer Shannon Larkin. Larkin joined Godsmack in 2002 and played on the albums Faceless, IV, the EP The Other Side, The Oracle, and their latest album 1000hp. The band has had three consecutive number 1 albums and has sold over 20 million records. In celebration of the band's success and the release of the 1000hp album in 2014, Boston mayor Marty Walsh declared Aug. 6 "Godsmack Day" in the city of Boston. One of the best rock shows I have seen was Godsmack with Sevendust last year. Incredible show!
