Moscow based musician Leonid Vorobyev has put together a band that sounds more like Chicago than Chicago! Leonid is the leader and founder of the band, Leonid & Friends. He is the band's producer, plays bass and piano, sings lead and backing vocals, transcribes all the musical scores and produces, mixes, and masters all their audio and video productions.
On his Facebook page Leonid recalls, "This was my crazy idea, in the fall of 2014, I had reached a pension age (60 in Russia) but I didn't want to retire, so I decided to make something special to celebrate the date". He gathered up some friends and covered the Chicago song, "Brand New Love Affair (Part I & II). The rest, as they say, is history.
Check out a video of his band performing "25 or 6 to 4" below:
