Watch the Ray's Messin' Around online guitar lesson by Jasper Mortier from 50 Blues Bass Licks You Must Know
This is a Two Step Piano Boogie. I think one of the most important things to realize with piano is that it's developed as a solo instrument with everything from the lows to the highs. This always creates a tension in a band because it kind of covers the whole spectrum from cymbals/snare of the drums through guitar all the way to the bass and the kick drum. So either the piano is backing up and kind of submerging in the rhythm section, adding more or less a flavor to the band. Or it's leading and you have to follow it in the rhythm section. In general I notice that piano players are often 'forward' players opposed to guitar players who are more often laidback players. Maybe it has to do with the fact that piano is acoustically not as loud as for instance the drummer. They had to develop this 'muscle' style of playing to catch up; almost automatically resulting in a pushing feel. Where the guitarist gets help from an amp and can turn up, developing a more relaxed playing style. Only in the 80-ies and 90-ies the piano players got help from the invention of digital piano's. This maybe explains the hate-love relation ship between piano and guitar.
