It reads: "Although music has always been his one great love, Erik studied drama and before joining the Butterfly, his acting ability had landed him the lead role in a local play.

Their music has found a significant impact on the international rock scenes, influencing numerous acts such as Black Sabbath, AC/DC, Rush, Alice Cooper, Mountain, Uriah Heep, Soundgarden, Stone Temple Pilots, Slayer, King Gizzard & the Lizard Wizard, and Queens of the Stone Age.

He was replaced in the line-up by two new musicians: guitarist/vocalist Mike Pinera (whose Blues Image had opened for Iron Butterfly's Vida tour) and guitarist Larry Reinhardt (from the Allman Brothers Band forerunner Second Coming).

Both Pinera and Larry "Rhino" Reinhardt had been rehearsing secretly with the band since September 1969 after Brann had voiced his objections to continuing.

In 1974, he was contacted by a promoter about reforming Iron Butterfly, so he reunited with Ron Bushy to form a new version of the group, signing with MCA.
