The frustration with attempting to just be seen as a serious rock band finally led to the break-up of the group. Carmen went into a solo career and his first outing was based on the 2nd movement of Sergei Rachmaninoff's Piano Concerto No. 2 in C Minor (interestingly enough, his second hit was also based on a piece by the same composer). It reached #2 on the charts in early 1976 and was the first of eight top 40 hits. It has spawned several dozen covers and launched Carmen into a success that eluded him with his previous group. Over the last decade or so, he works on projects now and then, and reunited with his former group for a tour and a fantastic live CD.
