Their first album ('Stray Dog', would you believe) is quite superb and well worth seeking out. It's got the 'Best Intro To Any Rock Song. Ever' (IMHO) on the opening track 'Tramp (How It Is)'. Completely wrong foots you.
Don't bother with the second album 'While You're Down There' as they added a keyboard player and a new vocalist which completely changed the dynamic for the worse.
