Marotta also spent a year in the early 70's as drummer for his own group; the short lived Brethren. Tom Cosgrove sang and played lead, Stu Woods played bass (he would later appear on Todd Rundgren's Something/Anything? album), and Mike Garson played keyboards. They released two albums; the first was just called Brethren and was mildly successful. The second, released as the band was crumbling is almost impossible to find. The band had a unique sound, a mixture of rock & country, with traces of jazz, and a bit of influence from Dr. John, who wrote the album notes and wrote a song ("Loop Garoo") for them.
He was also in a band called "The Riverboat Soul Band". They released their album in 1968 and it was called "Mess-up".
