Brass-heavy R&B group Tower of Power release their new album, ‘Soul Side of Town’, and the band celebrates the 50th anniversary of their founding on June 1. TOP’s anniversary, which will also include a concert, will be not be a silver anniversary in name only. Four of the founding members, Emilio Castillo, Dave Girabaldi, Stephen Kupka and Francis Prestia, remain with the band. Secondly, unlike many of their contemporaries from days with R&B giant bands ruled the earth, TOP never stopped working. They simply inserted a vocalist and kept it pushing.
