"I was trying to take the band in a direction that I thought was appropriate, and Roth was trying to take the band in more of a Las Vegas direction. And there he is"

This quote by Eddie Van Halen is referring to the creative distinctions between himself and former Van Halen frontman David Lee Roth. Eddie was attempting to take the band in a more musically appropriate direction, while Roth was attempting to take the band in a more business, Las Vegas-style direction. This quote is most likely referring to the fact that Eddie and Roth had various visions for the band, which Eddie was ultimately not successful in his effort to steer the band in the instructions he wanted. This quote also implies that Eddie was not delighted with the direction Roth was taking the band, and that he was eventually unsuccessful in his effort to take the band in a more musically appropriate direction. Ultimately, Roth's vision for the band triumphed, and Van Halen became an effective business rock band.
