          Re:  Artest Corporation Registration Statement on Form S-1
               for 5,000,000 Shares of Common Stock

Ladies and Gentlemen:

          We have acted as counsel to Artest Corporation, a Delaware corporation
(the "Company"), in connection with the proposed issuance and sale by the
Company of up to 5,000,000 shares of the Company's Common Stock (the "Shares")
pursuant to the Company's Registration Statement on Form S-1 (the "Registration
Statement") filed with the Securities and Exchange Commission under the
Securities Act of 1933, as amended (the "Act").

          This opinion is being furnished in accordance with the requirements if
Item 16(a) of Form S-1 and Item 601(b)(5)(i) of Regulation S-K.

          We have received the Company's charter documents and the corporate
proceedings taken by the Company in connection with the issuance and sale of the
Shares. Based on such review, we are of the opinion that the Shares have been
duly authorized, and if, as and when issued in accordance with the Registration
Statement and related prospectus (as amended and supplemented through the date
of issuance) will be legally issued, fully paid and nonassessable.

          We consent to the filing of this opinion letter as Exhibit 5.1 to the
Registration Statement and to the reference to this firm under the caption
"Legal Matters" in the prospectus which is part of the Registration Statement.
In giving this consent, we do not thereby admit that we are within the category
of persons whose consent is required under Section 7 of the Act, the rules and
regulations of the Securities and Exchange Commission promulgated thereunder, or
Item 509 of Regulation S-K.


                                                              Artest Corporation
                                                                          Page 2
