Billy Sheehan is perhaps best known as playing bass with Mr. Big and David Lee Roth. An accomplished solo artist, Sheehan recently released 'Holy Cow!,' an album mixed with instrumentals, interesting lyrics and collaborations with some of the biggest names in rock, including drummer Ray Luzier and legendary ZZ Top guitarist Billy Gibbons.

"That's probably the greatest thing that ever happened to me in my music career: having Billy Gibbons stop by my house and lay a solo down on a record of mine," Billy Sheehan told Noisecreep. "I was flying for days. It was a miracle, I couldn't be happier." Gibbons lays down intricate guitar work on "A Lit'l Bit'l Do It To 'Ya Ev'ry Time," but that isn't the only song on 'Holy Cow!' with a familiar guitarist handling the solo duties.

Paul Gilbert, a man Sheehan shared the stage with in Mr. Big, also appears on 'Holy Cow!' "The thing I love about Paul's solo on "Dynamic Exhilarator" is that it stars off slow, then it builds, it builds... at the end of the second part of the second solo, it just completely blows through the roof," explains Sheehan. "The dynamics of each section really track with the excitement level. He really did a great job. First time we recorded together since Mr. Big."

If playing bass seems to come naturally to Sheehan, singing isn't quite as effortless. "I'm funny about my voice," Sheehan admits. "I feel a lot more comfortable as a lead singer now on my third record than when I first started. I was fortunate enough to get a great vocal coach here in L.A. I'd sung my whole life and never really knew what I was doing. I just think I got more of it right on this record than before."
