Query: Highly Under Rated

One of REO Speedwagon's finest but it did not receive the credit it deserves. Been an REO fan since High Infidelity. Saw them live in 2010 and was blown away. Started replenishing my REO collection either on digital or CD format. Can't believe they released their first album in 1971. REO Speedwagon invented the power ballad genre but through all the personell changes they still know how to rock. One of America's finest bands.
